Rogue antivirus scammers have made $150M - 13/12/2009

Security experts call them rogue antivirus programs.

The FBI's Internet Crime Complaint Center issued a warning over this fake antivirus software Friday, saying that Web surfers should be wary of sudden pop-up windows that report security problems on their computers.

This software can appear almost anywhere on the Web. 

Last month, webcams sold by Office Depot contained links to a hacked Web site that tried to download rogue antivirus.
