have encountered this “ANTIVIRUS IS” program that stops the exe of any command and when it pops up it says you can buy it - the demo ver does not a remove feature. can’t do anything on that user Admin account. if i restart and go to another user admin account everything works ok. have run avast free on both accounts to no avail. any ideas?
Thats just scareware (a fake antivirus). If avast doesn’t detect it, try Malwarebytes Free.
+1 for MBAM.
A removal guide is also posted at Bleepingcomputer (and a few other places).
MBAM has the benefit of being excellent, and having a free version.
