Remove Win7 AV (Uninstall Guide)

  • September 3, 2010

Win7 AV is a rogue anti-spyware program that is installed through the use of malware and fake online anti-malware scanners. When browsing the web you may be shown a pop-up that states that your computer is infected. When you click on this pop-up you will brought to a site that shows a page that pretends to be a fake online anti-malware scanner, but in reality is just an advertisement. When the advertisement is finished it will state that your computer is infected and that you should download and install Win7 AV in order to protect your computer.

When Win7 AV is installed it will be configured to start automatically when Windows starts. Once started, it will scan your computer and report that there are numerous infections, but will state it will not remove them until you first purchase the program. The reality is that the infections it shows on your computer are either fake or legitimate programs that should not be removed from your computer. Therefore, do not remove anything that Win7 AV states are infections.

While Win7 AV is running it will also display fake security alerts while it is running. These alerts will contain messages that attempt to make you think that your computer is severely infected or that it is sending personal and private information to a remote computer. Win7 AV will also hijack your Internet Explorer, Firefox, or Chrome web browsers. When browsing the web with these browsers, Win7 AV will state that the site you are visiting is infected or has a security risk. These fake browser messages are:

In Firefox:

Reported Attack Site!
This web site has been reported as an attack site and has been blocked based on your security preference.

In Chrome:

Warning: visit this site may harm your computer

In Internet Explorer:

This is a reported phishing website
Internet Explorer has determined that this is a report phishing website. Phishing websites impersonate other sites and attempt to trick you into revealing personal of financial information.

Just like the scan results, these infection alerts and browser alerts are all fake and should be ignored.

Without a doubt, Win7 AV was created to trick you into thinking that you have a computer infection so that you will then buy the program. It goes without saying that you should definitely not purchase this program, and if you have, you should have contact your credit card company to dispute the charge. To remove Win7 AV please use 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 Win7 AV 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 Win7 AV 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 Win7 AV 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 Win7 AV . 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-1878.1878-3.0.6.1469.exe. 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.

  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.

    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 Win7AV 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.
