Doesn’t work.

First of all, access is still denied.
Secondly, the option won’t persist. When I come back to Options->Troubleshooting, it’s back on.

/edit
And forcibly terminating also doesn’t work

C:\Windows\system32>taskkill /f /im AvastUI.exe
ERROR: The process "AvastUI.exe" with PID 3168 could not be terminated.
Reason: Access is denied.
