There are many ways to uninstall Trellix software. Reasons for uninstallation might include migration to newer products such as Endpoint Security, or a need to clean up your system for maintenance purposes, with the intent to reinstall later.
The most common methods are:
- Migrations and upgrades using Endpoint Upgrade Assistant (EUA)
- The use of ePolicy Orchestrator (ePO) Client Tasks (see the "Uninstall product software from systems" section of the ePolicy Orchestrator Cloud Product Guide)
- Locally, using Windows Programs and Features (see KB83456 - How to remove Endpoint Security)
There are also instances where these methods might fail. You can use the EPR tool when these methods all fail.
IMPORTANT: Technical Support does not recommend using the EPR tool as your primary method to uninstall Trellix products, nor when you have uninstallation issues for the first time. The EPR tool is intended as a
last resort option when standard uninstallation methods have failed.
If you need the EPR tool
after all standard methods for uninstallation have proved unsuccessful, always make sure that you use the latest available version. You must not use an older version of the EPR tool to remove newer versions of Trellix software. If you try this, unexpected results might occur. For this reason, EPR tool releases are designed to expire every 90 days. For information about the latest versions of Trellix software that a version of the EPR tool can remove, see the user guide for that version of the EPR tool. This guide also outlines the supported Windows operating systems.
EUA can determine when product removal is needed before you install other software. So, if the goal of uninstallation is to install another version of a product, Trellix advises using EUA. For more information, see the latest version of the
Endpoint Upgrade Assistant Product Guide.
