There's a new twist with some fake antivirus scareware that has cropped up. It accepts payment via SMS, according to antivirus firm CyberDefender.
Typical rogue security programs infect the system first, then display pop ups warning that the computer is infected, and request payment to clean it up. The new programs are seemingly more genteel, asking for the money before the program is installed and infects the system, said Achal Khetarpal, threat research director at CyberDefender. Of course, a payment does nothing to "fix" a system and means criminals now have your money and possibly your credit card information.
