This section describes how to uninstall a password-protected agent from your Windows endpoint using the Windows Program Manager.

Important

A reboot is necessary after uninstalling Trellix Endpoint Security (HX) xAgent version 29.

Note

Artifacts that remain in the C:\Windows\FireEye folder after the agent software has been uninstalled will be deleted the next time the endpoint host is rebooted.

If a Windows xAgent uninstall attempt fails because the binary is missing or corrupt or because the 

ProgramData/FireEye
or 
Program Files/FireEye
directories are missing or corrupt, reinstall the agent using command-line commands (
msiexec /x <agent software installation msi file> /qn UNINSTALL_PASSWORD=password
) and then uninstall it.

To uninstall the Windows xAgent using the Windows Program Manager:

  1. In the Windows Control Panel, select Programs and Features. Depending on your version of Windows, you might have to select Programs before you can select Programs and Features.

  2. Locate  FireEye Endpoint Agent in the program list and right-click and select Uninstall.

  3. Select Yes when prompted to confirm that you want to uninstall the agent software and to similar confirmation prompts.

  4. When prompted, enter the uninstall password and click OK. If you are not authorized to remove the agent software from the Windows host or if you enter an incorrect password, the uninstall process will fail.
