Why do the anti virus programs become a virus? Yesterday, somehow, AVG AntiVirus FREE was installed on my computer. Never asking for my admin password. Of course my first indication was that it wanted me to update to the paid version. I said no, but it is still there. I just inserted a stick drive and it popped up asking if I wanted to scan it. Betting it won't uninstall easily. It now shows on my Win 10 program list as recently added. Surprisingly it appears to be popular legit anti virus program. Ugh.
