How to remove Antivirus (AnVi) malware (Uninstall Instructions)

Tell your friends:
Here's another rogue program with an original name: Antivirus. Actually, it's from the same family as Protection Center, Data Protection and Digital Protection scareware. The rogue program is installed through the use of Trojan Horses and other malware that come from shady or infected websites or through software vulnerabilities. You can use Secunia Online Software Inspector to make sure that your PC has a minimum security baseline against known patched vulnerabilities. Once installed, Antivirus will state that your computer has been infected with Trojans, adware, spyware, worms, tracking cookies and other malicious software. Then it will prompt you to pay for a full version of the program to remove the infections. Don't buy it! Instead, please follow the removal instructions below to remove Antivirus from your computer for free either manually or with legitimate anti-malware software.



Antivirus (AnVi) video (thanks to rogueamp):


While Antivirus is running it will attempt to uninstall your anti-virus or anti-spyware program from the system. It will also block all the other legitimate anti-malware programs and security websites. The rogue program does this in order to protect itself from being removed. What is more, Antivirus (AnVi) may come bundled with TDSS rootkit which usually redirects Google searc results to entirely unrelated websites. Most of the time, those website promote rogue products or provide false information, spam and etc. And of course, you wouldn't imagine a rogue anti-spyware program without a bunch of fake security warnings a pop-ups claiming that your computer is seriously infected or under attack from a remote computer. The text of some fake security alerts are:

"Warning! Virus threat detected!
Virus activity detected!
Net-Worm.Win32 has been detected. This adware module advertises websites with explicit content. Be advised of such content being possibly illegal. Please click the button below to locate and remove this threat."





It goes without saying that should uninstall Antivirus from your computer as soon as possible. If you have already purchased it then you should contact your credit card company immediately and dispute the charges. Then please follow free Antivirus removal instructions below. If you have a redirect virus alongside this rogue program, please use free TDSSKiller utility from Kaspersky lab. Also, your comments are more than welcome. Good luck and be safe!
