Several times a month I get the Anti-virus 2008 pop-ups while browsing. the fake scan comes up with enough hits that I doubt 6months of unprotected surfing on Mongolian snuff porns sites could produce. All of the little cute boxs like "hit ok to protect your computer now,or cancel to download program" come up,and the only way to stop it is to kill the Firefox with Task manager. Does just having the Hi-jack amount to infection? I never download the Exe,and afterward scans with Avira,Malwarebytes anti-malware, A-Squared 2,and super anti-spyware come up clean. I was told that in order for the Rogue program to seize the browser in this way, the system must be infected. In fact,I submited to a full malware removal operation at CastleCops without finding anything in the past. Should I go through the whole cleaning process with a Forum again?
