What is Antivirus System?
Antivirus System is a rogue antivirus program, which reports non-existent security infections in the hope that unsuspecting PC users will purchase a useless 'full version'. This program is created by cyber criminals in order to extort money and credit card information - it is a scam and should not be trusted.
Antivirus System originates from a family of fake antivirus programs called FakeRean and infiltrates users' operating systems (Windows XP, Windows Vista, Windows 7, and Windows 8) using any detected security vulnerabilities. Commonly, this rogue antivirus program is proliferated using 'exploit kits' via infected email messages, malicious websites, and drive-by downloads.
After successful infiltration, Antivirus System blocks execution of all installed software (including legitimate antivirus and anti-spyware programs), blocks Internet access (users are unable to launch Internet Explorer, Google Chrome, or Mozilla Firefox), and disables the Task Manager.
To scare computer users into purchasing the 'full version', this bogus software imitates a security check and simulates the detection of various high-risk security infections. Furthermore, Antivirus System generates security warning pop-ups, which indicate malware and viruses that are supposedly attacking the user's system.
If you observe this program 'scanning' your computer for security infections, you are dealing with fake antivirus software - do not trust it. The correct way to deal with it, is by removal from your computer.
Antivirus System is just one of many rogue antivirus programs, which attempt to sell useless license keys. Before purchasing security software to protect your computer, ensure that you read reviews and perform online research to avoid being tricked into buying a fake antivirus program.
If your computer is already infected with this rogue security scanner, ignore all 'security scans' and security warning pop-up messages, since this information is false. The only security threat you should worry about is Antivirus System itself. If your computer is already infected with this fake antivirus program, use the removal guide provided to eliminate this scam.

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.
