Hi Dan,
Right you are. I've been hit a few times with Fake-AntiVirus and I don't know where I get them.
Yes they completely knock out my system. As soon as it happens, nothing works.

This last time was the strangest.
I was not on the Internet browsing. My Computer was connected though, DSL, no browser was open. We use our PC for entertainment, Netflix DVDs and streaming. We popped in a DVD and we were about 30 minutes into the movie and BAMM, up pops the dreaded fake Alert Message and it was all over.
Every other time I was browsing online and when it happens everything just goes nuts. It never happenned like this before.
It was like a time bomb. This delayed attack was a shocker!
I do a full scan every night while I sleep and of course McAfee finds my system clean. But McAfee has NEVER stopped an attack. It has notified me and that I was infected. What a waste.
Wayne,
