I encountered a big problem for which I have not yet found a solution.
We have Avast Premium Security license.
After uninstalling with the uninstall tool, the internet connection was lost.
I see the following in the Windows Event log:
Several service not running, access denied. An "unknown" user appeared in process permissions and NT Service rights disappeared.
The problem is present on both Windows 10 and Windows 11 platforms.
Internet services are unavailable, the windows firewall cannot start.
What can be done? Quick help would be very important, because reinstalling the systems is not an option.
