Cloud AV 2012 virus - How to eliminate?

What is Cloud AV 2012?

Cloud AV 2012 is a fake computer security scanner that attempts to scare users into buying a fake license in order to remove non existent security threats 'detected' on your computer. This bogus computer scanner is derived from the same family of misleading security programs as AV Protection 2011, AV Security 2012, and many others. This fake security scanner is proliferated using Trojans and other rogue methods. Internet criminals create bogus websites and exploit security vulnerabilities in users' computers to distribute fake programs such as Cloud AV 2012. When your computer is infected with this fake program, your desktop will be flooded with fake security warnings and you will forced to observe a fake security scan each time you boot your operating system.

Cyber criminals designed Cloud AV 2012 with one purpose - to scare you into purchasing a fake computer scanner. If you have already bought Cloud AV 2012, you should contact your credit card company and dispute the charges, explaining that you have been tricked into purchasing a fake computer security program.

"Windows Security Alert. To help protect your computer, Windows Firewall has blocked some features of this program. Do you want to keep blocking this program? Name: Zeus Trojan Publisher: Unauthorized."

Other tools known to remove Cloud AV 2012:


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.
