AVG had detected some programs and system files as malware when they're core windows working files and applications, also legit applications from official websites and moved them to quarantine. Now I'm trying to restore them back and add them as an exception, AVG is throwing an error:
"Whoops, error occured. This file can't be restored"
I need those files back, my pc can't function correctly without them
