Compatibility with other installed products

Prev Next

Before you install Trellix Endpoint Security (ENS) 26.x, check that other products running on your endpoints are compatible. If any products are not compatible, follow instructions to resolve conflicts.

The installer detects existing virus-detection or firewall products on the endpoint, checks for compatibility, and tries to uninstall the software. If it can't, it prompts the user to cancel the installation, uninstall the incompatible software manually from the Windows Control Panel, then resume the installation.

Additionally, these products can affect the installation requirements for Trellix ENS or the way that Trellix ENS features are configured after installation.
