Then don't use Cheat Happens stuff. I even wasted my time looking up the detection name for that AV vendor since no one else did as they apparently don't care enough about their own computer security to know what it is that is "attacking" their computer to see if it was feasible that it got passed the AV or not despite the detection (and that AV product even conveniently links you to the knowledge base article on the detection report that you totally read).

It's a general warning about something that looks like malicious behavior. Nowhere in that page does it say that it is malware.
