How to remove Win7 AV malware (Uninstall Instructions)

Tell your friends:
Win7 AV is a fake anti-virus program that masquerades as legitimate security software. This rogue program pretends to scan your computer for malware and claims to find malicious files. Of course, the scan results are either false or grossly exaggerated because it flags harmless or non-existing files as worms, Trojans, dialers and other malware. What is more, Win7 AV forces to pay for a full version of the program to remove malicious files from your computer. Don't purchase it! It's a typical rogue anti-virus scanner that tries to deceive users into paying registration fees to remove malware from their computers. You should remove Win7 AV from your computer as soon as possible because it gives you a false sense of security. Thankfully, you can use legitimate anti-malware software to remove this rogue program from the system for free. Please follow our removal instructions below.

Win 7 AV comes from fake online scanners and misleading malware warning pages or through the use of Trojans. These fake warning pages look very genuine. They claim that the website you are about to visit is infected or malicious and claim that you should install reliable anti-malware software to protect your computer against various threats and viruses. If you choose to install their software you will end up with Win7 AV on your computer. These fake browser messages are:

In Internet Explorer:


In Mozilla Firefox:


In Google Chrome:


Once Win7AV is installed it will pretend to scan your computer and give exaggerated reports of threats. It will block legitimate anti-virus and anti-spyware programs and hijack web browsers. Then it will redirect your web browser to win7av.com which is the main web page of this rogue program to buy a license which costs $59.95 USD. Win7av.com impersonates the legitimate Microsoft Security Essentials web page.
