FBI Malware

So I was searching on google last night and clicked on one of the search links. Right away this crap popped up saying that the fbi has locked your computer and you have to pay $200 to unlock it lol... yea right. I did not download anything either right before or earlier that evening. This goes right past norton and must be self installing. It is a real pain in the butt to get rid of and as i said norton doesn't detect it yet. I ran an emergency boot but yea norton said the system was clean. I hope they add this one soon as it is a very very annyoying program.

 

BTW it seems to be web based as it won't pop up if you dissconect your internet connection.
