NOTE:This update has been changed from GA to RTS.
The reason is the issue described in: KB91642 - Reboot loop with Endpoint Security 10.6.1 July Update.
This update is available only by contacting Technical Support.
See the "Related Information" section below for contact details.
Issue: A blue screen error or hang might occur when the following actions are performed:
You install or upgrade a product with SysCore.
ENS Exploit Prevention or Host IPS Exploit Prevention is enabled.
The issue is timing-related and doesn't always occur.
Resolution: This issue is resolved in ENS 10.6.1 and ENS 10.7.0. A utility, mfeepmpk_utility.exe, is included in the ENS 10.6.1 installation packages to resolve the issue with the faulty driver. When you install or upgrade to ENS 10.6.1, the utility automatically detects whether the endpoint has the faulty driver. If it does, the utility replaces it to resolve the issue. If a restart is needed, a prompt displays on the endpoint to perform a one-time restart. The restart must occur for the installation or upgrade to continue. When the faulty driver is replaced, future installations and upgrades don't require a restart for this issue. See the related article for more information.

Issue: The 35111 events are generated on the endpoint and successfully delivered and uploaded to ePO by TA. But, ePO fails to parse the received events and so they don'tshow up in the ePO Threat Event Log for example. When the issue occurs, the managed product events sent to ePO aren't parsed and are added to the folder <ePO installation folder>\DB\Events\Debug.
Resolution: This issue is resolved in the ENS 10.7.0 November 2020 Update. See the related article for more information.
Issue: When ENS Threat Prevention Antimalware Scan Interface (AMSI) is enabled, Leica Cyclone software hangs at the Checking Licenses stage of the start process.

Issue: ENS Firewall allows and blocks network traffic through Firewall rules when the rule doesn't have a defined Executable FILE PATH value. This issue occurs with any Firewall rule that meets this criteria. But, it's commonly seen with the "Allow McAfee signed applications" rule within the default Firewall Rule policies.
Workaround: To work around this issue, review the existing Firewall rules in the Firewall Options and Firewall Rules policies. Any Firewall rule that has a defined Executable must have the FILE PATH criteria defined.

Issue: When you install ENS 10.7.0 using the standalone installer, and supply the verbose logging switch, the ENS installer doesn't write anything to the logs. Also, it doesn't install and almost immediately exits. (An example of a verbose logging switch is "setupEP.exe ADDLOCAL="tp,atp,fw" /l*v"C:\temp\ ".)
Workaround: To allow the successful installation of ENS using the standalone installer, remove the verbose logging switch from the command-line argument passed to the standalone installer.

10.6.1 February 2020 Update
Issue: Windows Backup Recovery might fail with ENS installed.
Resolution: This issue is resolved in the ENS 10.6.1 February 2020 Update and ENS 10.7.0 February 2020 Update.
Issue: After you install or upgrade to the ENS Threat Prevention 10.7.0 extension, all Medium-severity Exploit Prevention signatures change to enable the Block and Report setting within the Default policy. This function is a change from earlier ENS versions where Medium-severity signatures have Block and Report disabled by default. This change can possibly generate false positives in your environment, depending on the signature and coverage details.
Workaround: Use either of the following workarounds:
Modify the ENS Threat Prevention Exploit Prevention policy assigned to the systems and disable the Block and Report setting for Medium-severity signatures.
Review the ENS Threat Prevention Exploit Prevention Medium-severity events and determine whether a false-positive event occurred. If the signature isn't applicable to the environment, disable the signature.
Resolution: This issue is resolved in the ENS 10.7.0 February 2020 Update. See the related article for more information.
10.7.0 February 2020 Update
10.6.1 December 2019 Update
Issue: Windows Security Center (WSC) intermittently reports that ENS is disabled. WSC can prompt to enable Windows Defender.
Resolution: This issue is resolved in the ENS 10.6.1 December 2019 Update and ENS 10.7.0 February 2020 Update. See the related article for more information.
10.7.0 February 2020 Update
10.6.1 December 2019 Update
Issue: Defined ODSs don't run with a standalone installation. But, custom-defined scans run and complete.
Resolution: This issue is resolved in the ENS 10.6.1 December 2019 Update and ENS 10.7.0 February 2020 Update. See the related article for more information.
Issue: A core networking rule named "Allow McAfee signed applications" allows network traffic through the SYSTEM process. This fact affects SYSTEM-based network traffic, such as NetBIOS and SMB (for example, port 137, 138, and 445). If you create firewall rules to allow or block this type of SYSTEM-based network traffic, they don't apply. The reason is the "Allow McAfee signed applications" firewall rule is processed before any other firewall rules.
Resolution: This issue is resolved in the ENS 10.7.0 February 2020 Update. See the related article for more information.
ENSW-29097
10.7.0
Windows 10 Version 1803
Issue: A blue screen error (system crash) might occur when you try to upgrade to ENS 10.7 on Windows 10 Version 1709 (Fall Creators Update) and earlier.
Resolution: This issue is an operating system issue that Microsoft resolved in Windows 10 Version 1803 (April 2018 Update) and later. Before you upgrade to ENS 10.7, upgrade to Windows 10 Version 1803 (April 2018 Update) or later.
Issue: Blocking the protocols SSL v3 and TLS 1.0 leads to AMCore crashes.

10.7.0
Issue: Triggering the Threat Prevention Access Protection rule "Executing Windows Subsystem for Linux" references IDS_AP_RULE_PREVENT_WSL_EXECUTEION
:IDS_BLADE_NAME_SPB when describing the violated rule.This itemis a reference for the Access Protection rule "Executing Windows Subsystem for Linux."
Resolution: This issue is resolved in ENS 10.7.0. With ENS 10.7.0, IDS_AP_RULE_PREVENT_WSL_EXECUTEION:
IDS_BLADE_NAME_SPB is translated to the Access Protection rule "Executing Windows Subsystem for Linux."
Issue: After you uninstall the ENS Firewall module, all incoming traffic to the client is blocked.
Workaround: To prevent the issue, disable the ENS Firewall before you uninstall the module. In your assign ENS Firewall Options policy, deselect the option Enable Firewall. If you're uninstalling the ENS Firewall module locally, disable ENS Firewall through the ENS console. On clients that are already affected, reinstall ENS Firewall, disable ENS Firewall through your assigned policy, and uninstall the ENS Firewall module.
Resolution: This issue is resolved in the ENS 10.7.0 April 2020 Update. See the related article for more information.

Follow the prompt and install the app package.
Close the prompt.
Open Edge. An Enable WC Extension prompt appears.
Click Enable.
1254789
10.6.1
Issue: The Edge extension doesn't load on Microsoft Windows 10 Fall Creators Update and Windows 10 Creators Update even though the extension is licensed. A license issue reported by Microsoft causes this issue. We're working with Microsoft on this issue.
NOTE: The Edge extension isn't supported on the Windows 10 Anniversary Update. The native messaging that's needed to communicate between the extension and the Win32 process is introduced in the Windows 10 Fall Creators Update.
Workaround: The Edge extension is supported only on the Windows 10 April 2018 Update and later.
10.6.1
Issue: There's no group policy exposed to allow the ENS Web Control extension to use the InPrivate mode of the Edge browser.
Workaround: Manually allow the extension in InPrivate mode.
ENSW-13888
10.6.1
Issue: The ENS Web Control toolbar icon doesn't show the correct color depending on the rating of the website while switching between tabs. This issue occurs intermittently.
10.6.1
Issue: With the Windows 10 April 2018 Update, users can disable the Edge extension and bypass ENS Web Control protection.
Workaround: Windows 10 October 2018 Update provides a group policy (Prevent turning off required extensions) to harden the Edge extension. To make sure that users can't disable the Edge extension, add the ENS Web Control extension PFN to the group policy Prevent turning off required extensions. The ENS Web Control extension PFN is as follows and can be fetched from the Dev Center portal: 5A894077.McAfeeEndpointSecurityWeb
Control_wafk5atnkzcwy. For detailed instructions to enable this group policy, see Prevent turning off required extensions.
Issue: When ENSATP "Enable enhanced script scanning (includes AMSI integration)" is enabled in ENS 10.7 September 2023 Update, locally installed applications crash.
Workaround: Users can disable ENSATP "Enable enhanced script scanning (includes AMSI integration)" via ePO Remote Command.
ENSW-119209
10.7.0 April 2023 Update
Issue: When using the Threat Prevention extension from April 2023 update or later, to manage a November 2022 ENS client with a policy that contains multiple Exploit Prevention exclusions, only one exploit prevention exclusion is enforced on the client.
Workaround: Trellix has created a package that replaces the maspb.dll file on the November 2022 client.
To obtain the package, open a support case quoting reference ENSW-119209, and request that the package be sent to you.
IMPORTANT: The package updates the DLL binaries. Once you install it, upgrading to April 2023 isn't supported.
You must upgrade to the Q3 2023 ENS Release or later.
Solution: Upgrade to ENS client April 2023 or later.
ENSW-118918
10.7.0 April 2023 Update
Issue: When updating ENS 10.7.0 April 2023 GA to ENS 10.7.0 2023 Repost,
the Platform module is not automatically updated unless explicitly selected for the task.
Workaround: Include Platform module in any deployment task intended to update Endpoint Security 10.7.0 April 2023 GA to Endpoint Security 10.7.0 2023 Repost.
ENSW-118914
10.7.0 November 2022 Update
Issue: The File - Process - Registry exclusion can be added to the ePO policy for Exploit Prevention with only the name and signature ID fields defined, which excludes the rule in question.
Workaround: Make sure that other qualifying criteria are added to the exclusion to avoid excluding the rule.
ENSW-118911
10.7.0 November 2022 Update
Issue: Buffer Overflow exclusions that are invalid can be added to the ePO policy for Exploit Prevention with only the name field defined. All Buffer Overflow rules will be excluded as a result.
Workaround: Make sure that qualifying criteria are added to the exclusion to avoid excluding all Buffer Overflow rules.
Issue: The setupCC.exe executable crashes during an install of or upgrade to the ENS 10.7 November 2022 release.
Symptoms include the following:
Install or upgrade to ENS 10.7 November 2022 fails.
Application Event 1000 when setupCC.exe crashes.
"Install failed return code : 3221226505" in McAfee_Endpoint_BootStrapper_<date and time stamp>.log
McAfee_Common_BootStrapper_<date and time stamp>.log ends with “[BootstrapperMain] McAfee Agent could be installed on the system, if further checks pass.”
Workaround: You might be able to work around the problem through ePO Agent Handler configuration or by temporarily changing the Agent mode to unmanaged if only a small number of systems are affected. Contact Support if you want to pursue these options, and reference this Knowledge Base article.
Resolution: We have identified the cause of the crash and expect to include a fix in the next product release.
ENSW-117769
10.7 November 2022 release
Issue: Clients assigned to the read-only McAfee Default policy lose their policy assignment and revert to inheritance, when you update extensions to ENS 10.7.0 November 2022 release in ePO On-Prem.
Solution: It's not typical to have clients assigned to these policies in an ePO On-Prem setup.
But, after the upgrade finishes, re-assign them to the new "Trellix Default" policy post extension
Issue: After the installation of ENS ATP, the local client shows the correct settings as set in the policy. But, the registry values don't match.
Workaround: To have the correct values assigned, make an arbitrary change to each of these settings (contain, block, and clean levels) and enforce the change on the client. Then, revert to the original settings. See the related article for more information.
ENSW-116583
10.7.0 June 2022 Update
Issue: On Windows 10 version 1703 (Creators Update) and version 1709 (Fall Creators Update), ENS Threat Prevention installation might return an error due to the Microsoft Installer service restarting during installation.
Workaround: The Microsoft Installer service restarts after two minutes. Retrying the installation after that period results in success.
Issue: Enabling Exploit Prevention rules 6212 and 6213 (disabled by default) and using a third-party encryption application can cause a dead-lock that's seemingly random. This issue has only been observed in the presence of ZDK encryption software.
Workaround: These Exploit Prevention rules have been removed in Exploit Prevention content 12103 released on March 8, 2022. If you have this issue, and are using Exploit Prevention content before release 12103, disable the following Exploit Prevention rules:
IMPORTANT:After you disable or remove the rules, you need to reboot the system for the change to take effect.
See the related article for more information.
ENSW-115562
10.7.0 February 2022 Update
Issue: When Local Security Authority (LSA) is enabled on the client (by setting HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Control\Lsa\RunAsPPL to 1), the event for Credential Threat Protection no longer returns the target information.

ENSW-113668
10.7.0 September 2021 Update
Issue: When an ENS installation is paused because of a required update, the TA monitor shows an incorrect message. The message suggests that ENS Platform has installed successfully when it isn't installed and is waiting for the system to reboot.
The installation continues after you reboot the system and finishes successfully. The task isn't completed until the system reboots. The final status of the task shows the correct status.
ENSW-113638
10.7.0 September 2021 Update
Issue: Performing a standalone upgrade over ENS versions fails with TA 5.7.2 or earlier.
Workaround: Retrying the upgrade works, or you can uninstall ENS before installing the new version.
Issue: The default ENS Firewall rules block DNS name resolution and most network traffic from Windows Subsystem for Linux 2 (WSL2) and Docker instances. Windows Subsystem for Linux 1 (WSL1) isn't impacted.
Workaround: Create firewall rules to allow incoming traffic on the required local ports so that the default firewall rules don't block the traffic from the WSL2/Docker instance. See the related article for more information.
Issue: Potentially Unwanted Program exclusions aren't honored if "Scan processes on service startup and content update" is also set. Potentially Unwanted Program exclusions are defined at Endpoint Security Threat Prevention, Policy Category, Options, <policy name>, Exclusion by Detection Name. The scan processes setting is set at Endpoint Security Threat Prevention, Policy Category, On-Access Scan, <policy name>, Scan processes on service startup and content update.
Workaround: Disable the setting "Scan processes on service startup and content update." See the related article for more information.
ENSW-110567
10.7.0 April 2021 Update
Issue: ENS doesn't show as the registered antivirus product on Windows Server 2016, but Windows Defender is uninstalled.

10.7.0 April 2021 Update
Issue: For a directory with case-sensitivity disabled, after an enhanced remediation rollback, case-sensitivity is enabled if there's a symlink to the directory with case-sensitivity enabled. After a rollback, verify the case-sensitivity of the directory.
ENSW-110152
10.7.0 April 2021 Update
Issue: An enhanced remediation rollback restores the case-sensitivity settings of a directory, but a Quarantine recovery doesn't. Quarantine recovery doesn’t support case-sensitivity.
ENSW-110151
10.7.0 April 2021 Update
Issue: For a directory with case-sensitivity enabled that contains multiple files with the same name but a case variant, if case-sensitivity is later disabled, an enhanced remediation rollback only restores one of the files.
ENSW-109981
10.7.0 April 2021 Update
Issue: If you use the Windows Server Core user interface to set a custom ENS installation path, ENS is installed in the default location.
Workaround: Use the command-line parameter INSTALLDIR="C:\CustomFolder" to set a custom ENS installation path.
ENSW-109842
10.7.0 April 2021 Update
Issue: When the default ENS installation folder C:\Program Files\McAfee\Endpoint Security exists and has case-sensitivity enabled, ENS fails to install to a custom ENS installation path.
Workaround: Either delete the default ENS installation folder or disable case-sensitivity for the folder.
ENSW-109840
10.7.0 April 2021 Update
Issue: Access Protection rules don't work when MD5 is included on a path that has case-sensitivity enabled.
ENSW-109348
10.7.0 September 2020 Update
10.6.1 September 2020 Update
Issue: The Opera browser UI doesn't start on x86 platforms.
Workaround: Either use a different browser or uninstall ENS Web Control from the endpoint.
ENSW-106576
10.7.0 November 2020 Update
Issue: The ENS Exploit Prevention module remediates a Data Execution Prevention (DEP) violation. But, the event reporting that the remediation finishes successfully isn't sent from the client sometimes. The result might be that we remediate more DEP issues on the client system and report less of the remediated changes.
ENSW-106130
10.7.0 November 2020 Update
Issue: Tamper detection events aren't reported in the ePO console or ENS console. But, detection happens and you can see it in the Exploit Prevention logs.
ENSW-103559
10.7.0 September 2020 Update
10.6.1 September 2020 Update
Issue: You get an Access Denied error when accessing files on the C drive. The issue occurs if the Access Protection rule "Protect Endpoint Security logs folder" is enabled and you specify the ENS logs folder to be a common folder such as C:\, C:\Program Files, or C:\Windows. The rule protects the ENS logs folder from unauthorized processes. Only ENS processes have access to the folder when the rule is enabled. All other processes trying to create files, write files, and delete files within the folder are blocked.
Workaround: If you enable the rule "Protect Endpoint Security logs folder," don’t configure the ENS logs folder to be a common folder. We recommend keeping this folder isolated only for ENS logs and not sharing it for other purposes.
ENSW-98869
10.7.0 April 2020 Update
Issue: When you set Credential Theft Protection to "Observe mode," event description text incorrectly suggests that the detection is enforced.
Workaround: To view what action actually took place, see the "Action Taken" field. "Would Block" indicates an Observe-only action.
Issue: If a custom path is configured for Client logging, the ENS Product Logs folder might still exist after ENS is uninstalled.
ENSW-96724
10.7.0 February 2020 Update
Issue: The Limit maximum CPU usage option remains grayed out when Scan anytime is selected in the ePO extension.
ENSW-96670
10.7.0 February 2020 Update
Issue: The process mctray.exe might terminate unexpectedly when you update content via the V3 DAT exe.
Workaround: Run the V3 DAT exe again to restart mctray.exe.
ENSW-96274
10.7.0 February 2020 Update
Issue: In rare scenarios, the Threat Prevention policy changes might not be enforced on the client after the first agent-to-server communication.
Workaround: Settings get applied at the next agent-to-server communication of policy enforcement.
ENSW-29499
10.7.0 February 2020 Update
Issue: You deploy TA using the self-agent deployment URL with the Browsers launching files from the Downloaded Program Files folder Threat Prevention Access Protection rule set to Report. When you do, the Target Signed field in the resulting Access Protection event for McAfeeSmartInstall.exe is set to No.
ENSW-26135

ENSW-28892
10.7.0
10.6.1
Issue: ODSs with frequent pauses might rescan many files.
Issue: The Windows Event Viewer shows Security Audit Failure messages for amcfg.exe or fwwindowsfirewallhandler.dll. The ENS 10.7.0 February 2020 Update lowers the frequency of the messages being seen. There's no functional impact to ENS. We're investigating how to eliminate the events.See the related article for more information.
Issue: Creation of a downloadable agent installation package for non-Windows agents fails. An example of an agent installation package is TA for Linux. The failure occurs if ENS is configured to scan inside archives. The following error displays in the ePO console:
An unexpected error occurred
Workaround: On the ePO server, disable archive scanning. Disable the option Compressed archive files for the Standard Profile. See the related article for more information.
ENSW-96723
10.7.0
Issue: If the AMCore content version is 0.5 before upgrading to ENS 10.7, the AMCore version information is missing from the About field until the content is updated.
Workaround: To resolve the issue, update the AMCore content.
Issue: Upgrading to the ENS 10.7 extension results in the default ENS deployment task losing the ENS modules and repository branch information.
Workaround: To deploy the ENS modules, create a TA deployment task. See the related article for more information.
ENSW-29514
10.7.0
Issue: ENS upgrades use the cached ENS MSI databases. If you've deleted the cached ENS MSI databases from the C:\Windows\installer directory, ENS upgrades fail.
Workaround:
To prevent this issue from occurring, don't upgrade ENS. Instead, uninstall the current version of ENS and then install the new version of ENS.
If you've already encountered an upgrade failure, use the Endpoint Product Removal (EPR) tool to remove ENS and clean up the system. Then, install the new version of ENS. For more information, see KB90895 - Endpoint Product Removal tool to uninstall products.
Issue: When Windows Defender has content older than 1.295.49.0, it might generate a false-positive on one or more ENS installation files. As a result, the installation or upgrade of ENS fails or only partially succeeds.
Workaround: Before the install or upgrade of ENS, make sure that Windows Defender content is current or that Windows Defender is disabled.
Resolution: After you update the Windows Defender content or disable Windows Defender, the next attempt to install or upgrade ENS might succeed. If not, the failed installation might require removal first. See the related article for more information.
ENSW-28427
10.7.0
Issue: When you upgrade from VSE 8.8 Patch 9 (and earlier) to ENS 10.7, VSE remnants might be left behind.
Workaround: The following workarounds are available:
Uninstall VSE before you install ENS 10.7.
Upgrade VSE to 8.8 Patch 10 (or later) and then upgrade to ENS 10.7.
ENSW-28315
10.7.0
Issue: When you upgrade from Windows Server 2008 R2 to Windows Server 2019, the option to retain apps and data is disabled.
Workaround: Upgrade the operating system from Windows Server 2008 R2 to Windows Server 2019 before installing ENS.
ENSW-28558
10.6.1 October Update
Issue: In an environment that uses Microsoft SCCM, installation or upgrade of the Web Control module might fail.
Issue: The ENS Web Control browser extension doesn't appear in the Firefox 74 and later extensions list for new installations.
Workaround: Firefox 73 and earlier with the ENS Web Control extension enabled can be upgraded to Firefox 74 and later and retain the ENS Web Control extension.
Resolution: Use Active Directory (AD) to install the ENS Web Control extension. Firefox provides ADMX templates that you can use to configure an AD policy to enable the ENS Web Control extension. For instructions, see KB87568 - Web Control browser extension must be enabled by the user. See the related article for more information.
Issue: The application mfetp.exe crashes at module MSVCR100.dll.
Workaround: If an Exploit Prevention application protection rule is configured with over 50 executables, the process mfetp.exe crashes. Modify the Exploit Prevention application protection rule so that it has a maximum of 50 executables.See the related article for more information.
Issue: ENS for Windows doesn't support Windows dockers.
Resolution: We're investigating making ENS for Windows compatible with containers for future ENS releases. See the related article for more information.

ENSW-113340
10.6.0
Issue: In the following case, signer SDN matching doesn't work:
You create a Buffer Overflow exclusion where the Signature ID or API is specified.
The exclusion is based on an Exploit Prevention event.
Workaround: Reverse the order of the SDN element provided by the event. For example, if the threat event details specify the SDN as:
O=MCAFEE, OU=ENGINEERING, CN=TEST
Reverse the SDN order to:
CN=TEST, OU=ENGINEERING, O=MCAFEE
1235491
10.6.0
Issue: For AMSI file detections, where the First Action is Delete and the delete fails, the detection event incorrectly shows the Second Attempted Action as Not Available.
Workaround: No workaround is needed. The Second Attempted Action is Block and correctly blocks the activity.
EPO-8779
ePO 5.10.0 and ENS 10.6.0
Issue: The About box on the Endpoint Security Client is blank after a successful Exploit Prevention content update.
Workaround: Rebooting the system resolves the issue.
Issue: Scan resumed is output to the ODS activity log instead of Scan started when the setting Scan anytime - User can defer scans is enabled in the ODS task.
Workaround: Disable the setting Scan anytime - User can defer scans in the ODS task. See the related article for more information.
1213517
10.6.0
Issue: Communication is blocked for Microsoft Edge with Application Guard when you use ENS Firewall.
Workaround: Create a firewall rule with the following criteria: Allow Inbound TCP/IPv4 and TCP/IPv6, Local Ports 80 and 443 (or just the proxy port, when appropriate), Remote Ports 49700–65535, Virtual Media. We're investigating whether further qualifying criteria can be set for this rule to avoid the issue. This article is updated if new information becomes available.
NOTE:This rule also matches for VPN adapters. VPN traffic matching is disrupted.
1212361
10.6.0
Issue: After installation, the ENS Web Control module reports as "Not started" in the ENS console.
Issue: When an ENS Firewall rule is created using the Range option with either a single IP address or an IP subnet, the ENS Firewall console displays an incorrect Address Type (for example, Subnet). See the related article for more information.
1155117
10.6.0
Issue: You can't create a Threat Prevention Access Protection user-defined rule (also called custom rule) to include or exclude files that have no extension. ENS doesn't allow the administrator to distinguish between a file or folder when creating Threat Prevention Access Protection custom rules. This fact prevents the creation of custom rules that include or exclude files that have no extension.
1147465
10.6.0
Issue: There's no option to set a warn action for a website rated with a specific Web Category present in the Content Actions policy. (A warn action to display a warning page to the user to either continue or cancel the navigation of a website.)Only allow or block actions are available to configure for any website rated with a specific Web Category.
1106888
10.6.0
Issue: Exclusions aren't added to allow System Information Reporter 1.0 to work properly when the SIR Set Registry policy is changed.
NOTE:The System Information Reporter is EOL and no further action will be taken.
Issue: ENS Web Control reports in ePO can show a functional status for ENS Web Control in Chrome, Firefox, and Internet Explorer, and show in the report as True, Indeterminate, or False. But, on some systems, the computer can incorrectly report back a functional status of False.
Workaround: Use the ENS Web Control property enabled. See the related article for more information.

Issue: During an update, a crash can occur in Reputation Provider when a HostCommon update completes, but the ENS ATP update isn't complete. From the crash dump:
Workaround: Continue with the update until it succeeds for all ENS components. This issue is due to an incompatibility between Reputation Provider and the older version of ENS ATP. ENS doesn't support mixing versions of modules from different releases.

10.7.0 September 2021 Update
10.6.1 September 2021 Update
Won't fix
Issue: Upgrading an old ENS version (for example, ENS 10.6.0) to ENS 10.6.1/10.7.0 September 2021 Update or later fails.
Resolution: This behavior is as designed. Retrying the upgrade works. Or, you can first upgrade to ENS 10.6.1/10.7.0 June 2021 Update, and then upgrade to ENS 10.6.1/10.7.0 September 2021 Update or later.
Issue: Content Security Reporter (CSR) rejects logs from ENS Web Control if the logged on username contains a space.
Resolution: This behavior is as designed. CSR can't parse logs with a space in the username. Don't configure ENS Web Control to send logs to CSR if you have usernames with spaces.

Issue: Search annotations don't display in Mozilla Firefox or Google Chrome when searching in Google.
Issue: The ENS installation fails. The Common BootStrapper log shows the following error:
[BootstrapperMain] RunCommandLine: Process return code : 4294967295
[BootstrapperMain] !> Error - Could not run command to uninstall vscore helper util: -1
[BootstrapperMain] VSCore uninstall helper failed. Returning!!
Resolution: This behavior is as designed. The ENS installation and product functionality work whenminRSAPubKeyBitLength is set to the default value of 1024 bits. If you've overridden the default value, review and determine whether there's a compelling reason for the adjusted value. See the related article for more information.

Won't fix
Issue: The ENS Web Control Enforcement Messaging messages are truncated for Polish and Russian in the ePO policy.
Issue: When you create an exclusion for a process for Exploit Prevention signature 9990, the application continues to trigger signature 9990.
Resolution: This behavior is as designed. This workaround disables all ENS Buffer Overflow and Illegal API Use protection for the associated process. See the related article for more information.
Select Exploit Prevention event ID 18056 (Buffer Overflow detected and blocked (DEP)) in the Exploit Prevention Events log.
Choose Action, Add Exclusion.
Edit the added exclusion in the associated Exploit Prevention policy.
Remove signature ID 9990 from the exclusion.
Save the exclusion and policy.

10.6.0
As designed
Issue: ENS Web Control doesn't allow a clean file to download from a malicious URL based on reputation, if McAfee Client Proxy (MCP) is in redirection mode.
Resolution: This behavior is as designed. The file isn't downloaded because of a double enforcement by ENS Web Control and MCP. The recommendation is to enable the setting Disable if McAfee Client Proxy is detected in the ENS Web Control Options policy.
1228925
10.6.0
As designed
Issue: ENS installation might fail on a system with older update levels of Host Intrusion Prevention (Host IPS) 8.0.
Resolution: This behavior is as designed. Upgrade Host IPS 8.0 to one of the following:
Host IPS 8.0 Update 11
February 2018 content release 8231 (or later) if using Host IPS 8.0 Update 7 or earlier
March 2018 content release 8274 (or later) if using Host IPS 8.0 Update 8–10
Issue: If you install ENS Web Control on a system with Application and Change Control (ACC) 8.1.0.118.1 or later present, the Google Chrome Endpoint Security Web Control Extension is disabled (it's grayed out.) So, no sites are blocked and no ratings are shown.
Resolution: This issue won't be resolved. See the related article for instructions in the following scenarios:
To prevent the issue from occurring before you install ENS Web Control
To resolve the issue if you've already installed ENS Web Control and have experienced the issue.
1235803
10.6.0
Won't fix
Issue: In environments with short living processes with an unknown reputation, such as a compiler, ENS produces a performance penalty on the overall execution. This penalty occurs because the time needed to get a reputation is longer than the reputation retrieval.
Resolution: This issue won't be resolved. To avoid performance penalty, you can add an exclusion for the known path where the originator of the short living process resides. For example, the compiler path.

As designed
Issue: ENS ATP doesn't honor TIE and GTI Certificate Reputation.
Resolution: This behavior is as designed to prevent administrators from accidentally marking known trusted certificates with an override. This change can cause issues like blue screen errors with large enterprise applications.
Issue: If the ENS Web Control iFrames support feature blocks a site, adding the site to the ENS Web Control Allow List doesn't allow access to the site.
Resolution: This behavior is as designed. See the related article for more information. Use any of the following options to allow access to sites that the iFrames support feature blocks:
Add the IP address of the web server to the Exclusions list in the ENS Web Control Options policy.
Change the action specified for sites that are rated as Yellow and Unrated to Allow in the ENS Web Content Actions policy. Sites that are rated as Yellow and Unrated are blocked if the action specified for these sites is set to Warn and they appear in an HTML iFrame.
Disable the option Enable HTML iFrames support in the ENS Web Control Options policy.

Unable to reproduce
Issue: An ENS Firewall upgrade hangs.
Workaround: Perform the relevant option below:
For an ePO-managed environment: Create an ePO deployment task for the upgrade, and specify the following command-line parameter in the Command line text field:
-nopreservesettings
The parameter skips preserving settings during the upgrade and installs with the default policy. The client gets the customized policy in the next policy enforcement interval.
For a standalone environment: Don't select the Preserve Settings option in the installation wizard during the upgrade.

Issue: Access Protection rules for the Threat Prevention module aren't visible in the ePO console. An export of the policy (to XML) reveals that the value assigned to "APRules.dwAPRuleBlocks" doesn't match the actual number of rules.
Workaround: Delete the corrupt policy and create a new policy. Currently, the cause of the corruption is unknown.
1229445
10.6.0
Crowdstrike Hotfix is available
Issue: A system crash (blue screen error) occurs in mfencbdc.sys when installing ENS with the third-party software Crowdstrike present on the system.

Issue: Microsoft DEP integration works, but events aren't reported for buffer overflow attacks with standalone installations.
Resolution: This issue won't be resolved. DEP event reporting works as expected with ePO.
Issue: On Windows Server operating systems, web protection isn't blocking malicious sites in Internet Explorer 11.
Resolution: This behavior is as designed. On Windows Server operating systems, the Internet Explorer browser setting "Enable third-party browser extensions" is disabled by default. ENS Web Control requires this option to be enabled. For instructions to enable this option, see the related articles.
1214616
10.6.0
As designed
Issue: In an ePO deployment, the ENS installation is interrupted, leaving only the Platform installed.
Cause: Another application restarts the system after the Platform installation. Because of the restart, the TA deployment task is abruptly closed, which can cause ePO to not receive any response and then time out.
Resolution: This behavior is as designed. Send another deployment task to the systems with this issue. The ENS installation succeeds.

10.6.0
As designed
Issue: Access Protection File execute and Process run subrules and operations aren't working.
Resolution: This behavior is as designed. The service "McAfee Validation Trust Protection Service" allows trusted applications to function when needed. This service mitigates the risk of creating a rule accidentally that might prevent an essential process from running, and even impact the normal behavior of the operating system. The validation is applied only to some specific rules that are trusted from us and Microsoft. The validation is applied by default to all rules when created using the Access Protection user interface. But, the validation isn't applied by default for expert rules for Exploit Prevention.
10.6.0
As designed
Issue: Running the migration tool more than once can cause policies to be overwritten and appear to revert.
Resolution: This behavior is as designed. The policy migration task is intended to be run only once, and from that point, not run again in the environment.
Issue: After you install an ENS update or hotfix that upgrades AMCore, the AMCore scanner fails to initialize. On-Access Scanning and On-Demand Scanning don't work if the AMCore scanner doesn't initialize.
Resolution: This behavior is as designed. Anytime an ENS update or hotfix upgrades AMCore, it's mandatory to update to the current AMContent for the AMCore scanner to initialize. See the related article for more information.
1179963
10.6.0
Won't fix
Issue: When you use Kerberos authentication in the proxy server, Real Protect reports the connection failed and the ATP log reports RcStatus code 19. This issue occurs when the proxy server is configured by the IP address in the ENS Common policy setting and the ENS/Real Protect client fails to reach the proxy server. So, the Real Protect scan might make a direct connection.
Resolution: This issue won't be resolved. There's a known limitation in Kerberos. When you use Kerberos authentication in the proxy server, always configure the proxy server by fully qualified domain name (FQDN) or DNS name, rather than by IP address, in the ENS Common policy setting. (An example FQDN or DNS name is testkerbproxy.domain.com). For a system proxy in the Common policy, also follow the FQDN or DNS naming convention when you specify the proxy server in the browser proxy configuration. For example, in the browser manual proxy setting, and WPAD or PAC file.

10.6.0
Won't fix
Issue: The following migration issues occur when the ENS Firewall extension isn't installed:
Manual migration doesn't allow you to migrate VSE Access Protection and Buffer Overflow Protection (BOP) policies and Host IPS policies to ENS Threat Prevention policies.
Auto migration doesn't migrate trusted applications for Host IPS to the Access Protection policy as global exclusions.
The policy naming convention is different. The policy is named "Migrated VSE Policy-n" rather than "Merged Policy -n."
Resolution: This issue won't be resolved. Install the ENS Firewall extension even though you don't use the Host IPS firewall features.

Issue: Services protection doesn't block some services from starting. This issue has been reported with the Security Center Service and Bluetooth Support Service.
Issue: Installation of ENS fails. The installation logs contain error code 0x80096005, -2146869243, or both.
Cause: The required trusted root certificates aren't added during installation.
Resolution: This behavior is as designed. Address the issue preventing the automatic update of root certificates, or import the required root certificates. See the related article for more information.

Issue: Service protection has the following limitations (that also exist in Host IPS):
User and executable parameters aren't distinguished; although they're available in the UI, they aren't valid parameters.
Services protection is valid up to Windows 8.0; later releases aren't supported.
The enable or disable hardware profile operation isn't supported.
Resolution: This behavior is as designed.

As designed
Issue: After you disable firewall-timed groups, time ticking is paused when the firewall is disabled. It starts from the point in time when the firewall is re-enabled. Even though timed groups are enabled, they aren't functional because the firewall is disabled.
Resolution: This behavior is as designed. When the firewall is re-enabled, re-enable the timed group and change its running time in the policy. To stop the timed group, use the Disable Firewall Timed Group option in the McTray Quick Settings.

10.6.0
As designed
Issue: A process detected as malicious by Real Protect, its child process, and files dropped by the detected process, is sometimes not backed up using a single Quarantine ID. Remediation of Real Protect detection involves cleaning (Delete or Repair) of the process itself, child processes, and dropped files. During the remediation process, there's a possibility that some items might be cleaned by Engine and some might be cleaned by Real Protect. In such scenarios. Each item remediated by Engine is backed up in the Quarantine store with a different Quarantine ID. All items remediated by Real Protect have a single Quarantine ID. Usually, Real Protect cleans all items in a single quarantine session, so all items are grouped under a single Quarantine ID.
Resolution: This behavior is as designed. If you want to restore all items of a Real Protect detection, make sure that you look at multiple consecutive quarantine items (Grouped by Time Quarantined) in the Quarantine Manager. For a single remediation session of Real Protect detection, items remediated by Engine have the quarantine name with TIE/Suspect! and items remediated by Real Protect have the quarantine name that starts with Real Protect.
Issue: When ENS Web Control is installed on an operating system that has Internet Explorer with the Enhanced Protected Mode setting enabled, it fails to block malicious sites and file downloads. ENS Web Control isn't compatible with Internet Explorer Enhanced Protected Mode.
Resolution: This issue won't be resolved. See the related article for instructions to disable Enable Enhanced Protected Mode in Internet Explorer.

Issue: Real Protect doesn't delete the directories created by a malicious application. Real Protect remediates each item created or changed by the target application. But, the metadata about whether the item is created or changed isn't provided for remediation.
Resolution: This issue won't be resolved. The remediation module doesn't delete the directories to avoid loss of any other data.

Issue: You install ENS, enable Disable if McAfee Client Proxy is detected in the Options policy of ENS Web Control, enforce the policy, and then install MCP. But, ENS Web Control isn't disabled immediately after the installation of MCP.
Resolution: This behavior is as designed. Use either of the following workarounds:
Wait for about five minutes, and ENS Web Control is disabled.
Change any ENS Web Control policy and enforce the new policy, and ENS Web Control is disabled.

Issue: Block and Report settings of the Exploit Prevention policy aren't set when the Host IPS Rules Policy isn't edited, but the IPS Protection policy is changed. When the Host IPS Rules Policy isn't edited, but the IPS Protection policy is changed with the Reaction as either Log or Ignore, the Migration Assistant doesn't migrate the Host IPS Rules. The ENS settings are set to the default behavior.
Resolution: This issue won't be resolved. This issue is an unlikely scenario wherein the Host IPS Rules policy isn't edited and the dependent IPS Protection policy is changed to a lower Reaction for high-severity signatures. Even though this configuration might have been made by mistake, ENS defaults to correct the behavior with setting the Block setting.

Issue: If an TA update task is configured to show the update progress window, and the user is allowed to postpone the task, the "Update in Progress" window might appear for a short time. It appears even though the update isn't actually occurring. If the user postpones the task, an "Update finished" window might appear, even though the update didn't occur.
Issue: A scan exclusion configured for multiple mount points doesn't work.
Workaround: Configure the scan exclusion with the full path for the mount point. If you experience this issue, contact Technical Support. See the related article for more information.

Won't fix
Issue: After all ENS modules are uninstalled, the Common module (ENS Platform) uninstallation is automatically started. Sometimes, the user interface for this uninstallation is minimized. This fact can make it more difficult for a user to tell when this uninstallation occurs.
Cause: The ENS Platform is a support module that's needed for the ENS protection modules to function. When all other modules are uninstalled, the ENS Platform module is automatically removed. But, Windows sometimes starts this process in a minimized mode or shows the window behind the other windows on the screen. If the user doesn't know that this uninstallation is happening, they might inadvertently restart the system in the middle of that uninstallation.
Resolution: This issue won't be resolved. Before you uninstall ENS products, make sure that any current work is saved, and close running desktop programs. The user can likely see that the ENS Platform uninstallation is occurring.

Issue: If you upgrade the Threat Prevention extension version, the ENS client UI might fail to display Exploit Prevention exclusions, indicate erroneous validation errors, and generate errors in EndpointSecurityPlatform_Errors.log such as the following:
Failed to retrieve GPEP setting for Exploit Prevention.
Failed to enforce Exploit Prevention policies.
Resolution: This issue won't be resolved. Edit and save the assigned Exploit Prevention policy, and send an agent wake-up call to the affected systems.
Issue: On Windows 7, user roaming profiles aren't saved to a network share on user logoff.
Workaround: Create an exclusion in Threat Prevention to not scan the roaming profile folders on the server. See the related article for more information. Currently, a root cause can't be found on Windows 7. If you experience the issue with Windows 8 or Windows 10, collect the information described in the related article and provide the results to Technical Support.

Issue: When a deployment task for ENS fails because of an insufficient version of TA, the TA Monitor displays a message that says the task is successful.
Resolution: This behavior is as designed. Ending the deployment process during the prerequisite software check isn't considered a failure state by TA. The deployment doesn't continue to the download phase. As far as TA is concerned, the task itself is successful in running, even though it ends prematurely. This behavior is different from when the deployment fails while running the installation program after it has been downloaded to the endpoint.

Depending on how often your system is designed to run an audit, you might see several of these errors in the Windows Event Log.

Issue: Some informational common settings for modules still exist in the Common settings page even though the module isn't installed. For example, Threat Prevention events aren't removed after the related blades are uninstalled from the system.
Resolution: This behavior is as designed. No problems occur because of the existence of these settings.

Issue: The local update task doesn't run at the specified time, but instead runs later.
Resolution: This issue won't be resolved. To avoid a network storm, the local update task uses a randomization of 60 minutes when setting up the schedule. So, the update task runs within 60 minutes of the scheduled time. The randomization setting isn't available from the local UI and can't be changed.

Issue: A sharing violation error is logged in the local log file after scanning the C:\Windows folder. The sharing violation is expected because of the files being open exclusively (no shared read) in Windows processes.
Resolution: This behavior is as designed. The sharing violation error severity is set to Informational. This fact means that by default, the error isn't sent to ePO. Also, the error doesn't display in the Windows Event Log by default.

Issue: Some Access Protection rules protect against remote access, such as the Remotely accessing local files or folders rule. When these rules are enabled and an access is reported or blocked, the target path value in the Event Log might report the pipe connection. It can report the pipe connection rather than the file path that's requested in the access that's attempted. For example, the Event Log might report \\.\pipe\srvsvc rather rather than \\computer\share\filename.
Resolution: This behavior is as designed, and is a reflection of how the Windows file system works.

Issue: An erroneous summary is displayed in the Threat Summary: Threat free for last 30 days if ENS is installed in the last 30 days.
Resolution: This behavior is as designed. If there have been no threats in the last 30 days, ENS displays this message. If there have been threats in the last 30 days, ENS displays the exact number of threat-free days.

10.6.0
As designed
Issue: There are no Self-Protection events in the Windows Event Viewer, ENS Client Event Viewer, or ePO Threat Events.
Resolution: This behavior is as designed. Self-Protection events are set to Informational by default and they're tied to the Event Filtering of Access-Protection. All event filtering is set to Major and Critical by default in ePO and in the client UI. To see Self-Protection events in the Windows Event Viewer, the ENS Client Event Viewer, or ePO Threat Events, you must change the Event Filtering for Access-Protection to All. Because All includes informational events, Self-Protection events display in the three areas mentioned.
NOTE:Regardless of the Event Filtering settings, Self-Protection events are logged to the SelfProtection_Activity.log file located in %PROGRAMDAT%\McAfee\Endpoint or %allusersprofile%\application data\McAfee\Endpoint. You can view this information at any point if needed.

Issue: Clicking Update Now reports a successful update when the system is already up to date.
Resolution: This issue won't be resolved. When you click Update Now, the updater is initiated and the repository is checked for new updates. This behavior occurs regardless of whether the system is already up to date. Even in the case where no update is applied, the updater reports that the update is successful.
Issue: A reboot loop can occur after you install or upgrade to ENS 10.6.1 July Update. The issue occurs only if other Subject Interface Package providers are present and Exploit Prevention is enabled.
Resolution: This issue is resolved in the ENS 10.6.1 July Update Repost. See the related article for more information.
Issue: The ENS ATP service (mfeatp.exe) might crash with a reference to the DLL ReputationProvider.Dll. When a crash occurs, the ENS ATP service automatically restarts about 10 minutes after the crash. The crash can reoccur. If the crash reoccurs, the ENS ATP service automatically restarts.
Resolution: This issue is resolved in the ENS 10.6.1 July Update Repost and ENS 10.6.1 Hotfix 190501. See the related article for more information.

Issue: A small kernel memory leak in tags CMNB and CM31 occurs with Real Protect enabled on server operating systems.
Workaround: To mitigate the issue, disable Real Protect.
Resolution: Microsoft handling of Event Tracing for Windows (ETW) causes this issue. Real Protect uses ETW tracing. This issue is resolved in Windows Server 2016 and in a Windows Server 2012 update (KB4489881 update).
Issue: After Threat Prevention is installed, Windows Server 2012 or Windows Server 2012 R2 servers with Cluster Shared Volumes randomly experience a system crash (blue screen error).
Workaround: The issue doesn't occur with Windows Server 2016.
Resolution: There's a Microsoft release that resolves this issue, which is described in the March 2017 rollup. See the related article for more information.
