I just wasted my lunch break (and then some) on the phone playing computer tech support for my Dad.
He caught a nice case of this:

It's a fake virus scanner that is itself a virus. The best part: if you're dumb you can pay $90 for the opportunity to own the full licensed version of the virus! Luckily my Dad didn't get that far because he noticed the spelling errors in the fake virus warning messages and called me.
Unfortunately, the damn thing is smart enough to detect when you're downloading the anti-spyware programs that will get rid of it and it cancels the download before they complete. Fucking awesome.
So, it looks like the next time I'm down to my parent's place, I get to hack at a crappy virus. I think I'll just format the bitch and reinstall windows.
