How to remove Antivir (Uninstall instructions)

Antivir_scan_completeAntivir is is not a legitimate security application. The program is a rogue antispyware program that spreads mostly with the help of fake online malware scanners. It will report that your computer is infected and you must install Antivir to clean your PC. That online scanner is scam and could not possibly detect malware, trojans and viruses on your computer.

When Antivir is downloaded and installed, it will be configured to run each time when you login to Windows. Once started, it will start a scan of your computer and list a lot of infections to scare you into thinking that your computer is infected. All of these infections are fake and cannot harm your computer. The rogue uses the false scan results as method to trick you into purchase so-called “full” version of the software.

Antivir blocks the ability to run some programs. The following warning will be shown when you try to run the Notepad:

Antivir Resident Shield: Virus Detected
Warning! Active virus detected

While Antivir is running your computer will display nag screens, warnings and fake security alerts from your Windows taskbar. It will state that trojan activity detected or identity theft attempt detected. Some of the alerts:

Internet Shield: Identity theft attampt detected
Warning! Identity theft attempt detected

Trojan:W32/Inject Activity Detected
Trojan:W32/Inject is a large family of malware that secretly
makes changes to the Windows Registry. Variants in the
family make also makes changes to other running processes.

Adobe Acrobat and Adobe Flash Errors Found
A vulnerability in Adobe Acrobat, Adobe Reader, and
Adobe Flash can result in remote code execution or virus

What is more, the program will hijack Internet Explorer and randomly shows a “Warning! Visiting this site may harm your computer!” warning page.

However, all of these warnings are fake and supposed to scare you into thinking your computer is in danger. You should ignore all of them! If you find that your system is infected with this malware, then most importantly, do not purchase it. Use the removal guide below to remove Antivir from your computer for free.

    Comment by Cameron — December 7, 2009 #

  13. Why is it this AntiVir is able to get passed ENOD, Norton and most importantly, Windows Security? What the hell is going on with that? I was able to uninstall it. I am sure Windows is aware this bunch of thieves are using a symbol that is identical to their Security icon in the upper left hand corner. Microsoft needs to get on the ball and prepare a security update against this type of stuff.

  27. To clariify my last post, you can get to the avenger site by opening up the Windows Update window, then browse from it to the site in question to download the removal tools.

    Certainly did the trick for me and excluding the download time probably only took 20 minutes to complete. NICE ONE!
