Summary:

The fake antivirus programs (also known as "rogue antivirus programs" or "scareware") are applications that tries to lure computer users into paying for their non-existent full versions to remove the supposedly detected security infections (although the computer is actually clean). These bogus programs are created by cyber criminals who design them to look as legitimate antivirus software. Most commonly rogue antivirus programs infiltrate user's computer using poop-up windows or alerts which appear when users surf the Internet. These deceptive messages trick users into downloading a rogue antivirus program on their computers. Other known tactics used to spread scareware include exploit kits, infected email messages, online ad networks, drive-by downloads, or even direct calls to user's offering free support.

A computer that is infected with a fake antivirus program might also have other malware installed on it as rogue antivirus programs often are bundled with Trojans and exploit kits. Noteworthy that additional malware that infiltrates user's operating system remains on victim's computer regardless of whether a payment for a non-existent full version of a fake antivirus program is made. Here are some examples of fake security warning messages that are used in fake antivirus distribution:

Computer users who are dealing with a rogue security software shouldn't buy it's full version. By paying for a license key of a fake antivirus program users would send their money and banking information to cyber criminals.
