Silent uninstall unmanaged Avast EPS on domain PCs
« on: June 28, 2018, 02:26:00 PM »
I have about 60 PCs on which unmanaged Endpoint Protection Suite is installed. Is there any script avaliable for silent uninstall that I can mass deploy in domain? I already have managed Avast Business Pro ready for deployment. Any help would be appreciated.

The command-line to uninstall Avast Endpoint Protection from the system is:

cmd  /c "C:\Program Files\AVAST Software\Avast Business\Setup\setup.ovr" /uninstall /cleanall /verysilent /reboot 30

Note: The uninstallation requires a reboot to delete the Avast Antivirus services and unload its' associated kernel and file-system drivers from the working system.

GOD BLESS YOU! I was stuck with an old Avast Endpoint Management console that would not launch in addition to losing the management password. Your script saved me tons of time. I created a scheduled task GPO to run that command and quickly saw my environment's old Avast installs disappear.
