A-Fast Antivirus is a rogue anti-spyware program that uses misleading methods to scare users into thinking that their computers are infected with malware. It uses javascript and css within your web browser, including MSIE and Firefox, to mimic another well known antivirus program. It has been dubbed "scareware" by some writers.

A web site has malicious javascript code that causes an interface to appear, mimicking a legitimate looking antivirus scanning software. If you click one of the popups it installs a rogue security application.

A-Fast is known by other names:

• Critical System Warning!
• Fast Windows Antivirus
