ESET Endpoint Antivirus and ESET Endpoint Security version 6.6.2072.2 and 6.5.2118.2 have been released.

This release resolves an issue with the most recent Windows Update distribution. 

Endpoints versions 6.6.2072.0 and 6.5.2118.0 with the most up-to-date Anti-Stealth module DO NOT need to upgrade to this new build

The Anti-Stealth module was updated per normal module update process and existing Endpoint installations that receive the regular module updates do not need to be updated. 

Check for latest Anti-Stealth module (optional, and only for existing installations)

From the client workstation (or you can use RDP to check remotely), from the main program window click Update Show all modules. The updated module is 1120. 


  • Fixed: Stop error (BSOD) in Anti-Stealth module on Windows 10 x86, as a result of OS update series remediating critical vulnerabilities in processor architecture (KB4073291).
