Problem

Some applications fail to function correctly when third-party antivirus/antimalware software is installed. The issue occurs when the Exploit Prevention feature of the ENS Threat Prevention module is enabled. For a list of known third-party antivirus/antimalware software with which this issue occurs, see the Environment field of this article.

Some examples of application failures include:

Microsoft Office applications such as Word or Excel might fail to start and might not spawn a process in Task Manager.
Adobe applications do not open PDF files.
Web browsers (for example, Internet Explorer) do not load pages.

System Change

You installed or upgraded to ENS 10.x and installed third-party antivirus/antimalware software.

Solution

Remove the third-party antivirus/antimalware software. ENS Threat Prevention does not support working with other products with the same function.

Workaround

Disabling the Exploit Prevention feature of ENS Threat Prevention can prevent this issue. But, disabling Exploit Prevention is not recommended.
