Remove AntivirusGT (Uninstall Guide)

  • July 5, 2010

AntivirusGT is a rogue anti-spyware program that is distributed through the use of fake online anti-malware scanners. When browsing the web you may be redirected to a page that states that your computer is infected. This page will then prompt you to perform an online anti-malware scan on your computer in order to search for viruses. Regardless of whether you accept this offer, you will be brought to a page that displays a fake scanner, that when finished scanning, will state that your computer is infected. It will then prompt you to download and install AntivirusGT in order to remove these supposed infections. It should be noted that this fake scanner page does not actually scan your computer. Instead it is simply an advertisement that will state that your computer is infected no matter how clean it may be.

Once AntivirusGT is installed on to your computer, it will be configured to start automatically and then scan your computer. When it has finished scanning your computer the program will state that there are numerous infections present on your computer, but will not allow you to remove any of them until you first purchase the program. These infections, though, are actually legitimate programs that if removed may cause your computer not to start or operate properly. Therefore, do not manually delete any of the files it states are infections as you will be deleting legitimate and required Windows programs.

While running, AntivirusGT will also attempt to protect itself by not allowing you to run various programs. It does this so that you cannot run security programs that may assist you in removing this infection. When you attempt to run a program you will instead see a message stating that the file is infected. An example of this fake security warning is:

AntivirusGT Resident Shield: Virus Detected
Warning! Active virus detected!
Threat Detected: Trojan.Injector.BZ
Infected File: C:\Windows\System32\rundll32.exe

When AntivirusGT is no longer running you will then be able to run your applications like normal.

While started, AntivirusGT will also display fake alerts that state your computer is under attack or that there are new Windows updates available. When you try to fix the errors or install the updates, though, it will instead prompt you to purchase AntivirusGT. An example of the security update alert is:

Security advisor: Important updates available
New important updates available:

Virus and spyware database is out of date.
New Important updates:

 - antivirus database definitions update
 - anti-spyware database definitions update
 - critical system vulnerabilities fix
Optional Updates
 - resident shield update
 - Internet Explorer potential vulnerabilities fix

The infection will also hijack your Internet Explorer browser so that when you are browsing the web you will be randomly shown an alert stating that the page blocked you from accessing because you are infected. The text of this alert is:

Attention! Your web page request has been cancelled.
This web site refused your connection as it was reported as a malicious request. This can be caused by Viruses, Trojans or Malware installed on your computer.

In order to resend your request to the website, press Resend request (please note, this action may cause a permanent block of your computer by the requested website)

In order to activate your security software, please press Fix Now (recommended)

All of the above alerts are fake and are only being shown to scare you into thinking that you have a security problem and should be ignored.

As you can see, AntivirusGT was created to trick you into purchasing the program by making you think that your computer is infected. As all of these alerts and scan results are fake, you should not purchase this program for any reason. If you have already purchased it, then we suggest you contact your credit card company and dispute the charges stating that it is a scam. To remove AntivirusGT please follow the steps in the removal guide below.

Self Help Guide

This guide contains advanced information, but has been written in such a way so that anyone can follow it. Please ensure your data is backed up before proceeding.

If you are uncomfortable making changes to your computer or following these steps, do not worry! Instead you can get free one-on-one help by asking in the forums.
  1. Print out these instructions as we may need to close every window that is open later in the fix.

  2. It is possible that the infection you are trying to remove will not allow you to download files on the infected computer. If this is the case, then you will need to download the files requested in this guide on another computer and then transfer them to the infected computer. You can transfer the files via a CD/DVD, external drive, or USB flash drive.

  3. Before we can do anything we must first end the processes that belong to AntivirusGT so that it does not interfere with the cleaning procedure. To do this, please download RKill to your desktop from the following link.

    RKill Download Link - (Download page will open in a new tab or browser window.)

    When at the download page, click on the Download Now button labeled iExplore.exe download link. When you are prompted where to save it, please save it on your desktop.

  4. Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with AntivirusGT and other Rogue programs. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and you can continue with the next step. If you get a message that RKill is an infection, do not be concerned. This message is just a fake warning given by AntivirusGT when it terminates programs that may potentially remove it. If you run into these infections warnings that close RKill, a trick is to leave the warning on the screen and then run RKill again. By not closing the warning, this typically will allow you to bypass the malware trying to protect itself so that rkill can terminate AntivirusGT . So, please try running RKill until the malware is no longer running. You will then be able to proceed with the rest of the guide. If you continue having problems running RKill, you can download the other renamed versions of RKill from the rkill download page. All of the files are renamed copies of RKill, which you can try instead. Please note that the download page will open in a new browser window or tab.

    Do not reboot your computer after running RKill as the malware programs will start again.

  5. At this point you should download Malwarebytes Anti-Malware, or MBAM, to scan your computer for any any infections or adware that may be present. Please download Malwarebytes from the following location and save it to your desktop:

    Malwarebytes Anti-Malware Download Link (Download page will open in a new window)

  6. Once downloaded, close all programs and Windows on your computer, including this one.

  7. Double-click on the icon on your desktop named mb3-setup-1878.1878- This will start the installation of MBAM onto your computer.

  8. When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, make sure you leave Launch Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes prompts you to reboot, please do not do so.

  9. MBAM will now start and you will be at the main screen as shown below.

    Malwarebytes Anti-Malware

    Please click on the Scan Now button to start the scan. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.

  10. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.

    Malwarebytes Anti-Malware

  11. When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different than what is shown in the image below due to the guide being updated for newer versions of MBAM.

    MalwareBytes Scan Results

    You should now click on the Remove Selected button to remove all the seleted malware. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.

  12. You can now exit the MBAM program.

  13. As many rogues and other malware are installed through vulnerabilities found in out-dated and insecure programs, it is strongly suggested that you use Secunia PSI to scan for vulnerable programs on your computer. A tutorial on how to use Secunia PSI to scan for vulnerable programs can be found here:

    How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector


Your computer should now be free of the AntivirusGT program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
