Hacked Facebook Apps Lead to Fake Antivirus Software

New applications are turning up on Facebook. Unfortunately, some of them are fake antivirus programs.

While researching Web sites that host malicious software, Roger Thompson, chief research officer of software security company AVG, noticed something funny. A Russian Web site known for hosting malware was getting lots of referrals from Facebook.

On further investigation, Thompson found the referrals were coming from a Facebook application called "City Fire Department," a game where multiple players respond to emergency calls. The application had been modified to deliver an iframe, which is a way to bring content from one Web site into another.
