What is AntiVira Av?
AntiVira Av is malicious software created by Internet criminals with the purpose of tricking computer users into purchasing a license key to remove ‘security threats’ which do not actually exist. This program generates a list of critical risk security infections and then coerces users into buying a license to remove them.
This fake program is designed to steal money from your bank account. It hijacks your Internet browser and blocks legitimate Windows applications.
This software is a scam, completely useless, and should be removed from your computer immediately.
If you have already purchased a fake license for this software, you should contact your credit card company and explain that you have been tricked into buying a fake antivirus program. This fake program is distributed by various infected websites, spam emails, and Trojans.
The creators of this bogus program also use Twitter, Facebook, and other social networks to propagate this scam. After installation of this fake software, it will configure itself to run automatically on system start-up.
The software will block your desktop and perform a fake security scan. After the scan, AntiVira Av will report that your computer is infected with various viruses and spyware.

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. Users who have already entered their credit card number (or other sensitive information) when asked by such bogus software should inform their credit card company that they have been tricked into buying a rogue security software. Screenshot of a web page used to lure computer users into paying for a non-existent full version of antivira antivirus and other rogue antivirus programs:
To protect your computer from antivira antivirus and other rogue antivirus programs users should:
- Keep their operating system and all of the installed programs up-to-date.
- Use legitimate antivirus and anti-spyware programs.
- Use caution when clicking on links in social networking websites and email messages.
- Don't trust online pop-up messages which state that your computer is infected and offers you to download security software.

- Alerts asking to upgrade to a paid version of a program to remove the supposedly detected malware.
