Remove Windows Antivirus Pro (Uninstall Guide)

  • July 26, 2009

Windows Antivirus Pro is a rogue anti-virus program and a ransomware that does not allow you to run any programs on your computer. When Windows Antivirus Pro is installed it is configured to run every time Windows starts. Once running it will automatically scan your computer and then list a variety of infections that you cannot attempt to remove until you purchase the program. This program also acts as ransomware because while it is running it will state that almost any program you try to execute is an infection and not allow you to run it. This makes it hard to run any legitimate anti-malware programs until you end the Windows Antivirus Pro processes or purchase it.

  1. Print out these instructions as we may need to close every window that is open later in the fix.

  2. This application will disable the ability to use your Windows Task Manager. To fix this, please download the following file to your desktop.


    Once the file is downloaded, double-click on it and select Yes when it asks if you want to merge the data into your Registry. Once that is completed you should be able to use the Windows Task Manager.

  3. Now we need to end the two processes associated with Windows Antivirus Pro as they do not allow you to run any applications that we will need to remove this program. To do this we need to launch the Windows Task Manager by right-clicking on the time in the Windows task bar and then selecting Task Manager. The menu showing the Task Manager option is shown below.

    Launch Task Manager

  4. When Task Manager is started you will be in the Applications section as shown below.

    Task Manager Applications Tab

    At this point you should click on the Processes tab.

  5. You will now be at a screen that shows the running processes on your computer. First put a checkmark in the checkbox labeled Show processes from all users as shown in the image below.

    Processes tab of Task Manager

    Then scroll through the list till you see the process called Windows Antivirus Pro.exe and left-click on it once so it becomes highlighted. Then click on the End Process button as shown by the red arrow in the picture above.

  6. When you click on the End Process button, Task Manager will ask you to confirm if you are sure you want to terminate it as shown in the image below.

    End Process in Task Manager

    At this point you should press the Yes button in order to kill the process.

  7. After you have ended the Windows Antivirus Pro.exe process, scroll through the list of processes until you find the svchast.exe process. Then end this process as well by clicking on the End Process button and confirming that you want to end it. Please note that in Windows there is a legitimate program called svchost.exe, so please be careful to only end the process that is spelled svchast.exe.

  8. Now that the two Windows Antivirus Pro processes are terminated, you can use your programs again. You should now download Malwarebytes Anti-Malware, or MBAM, from the following location and save it to your desktop:

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

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

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

  11. 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 both the Update Malwarebytes Anti-Malware and Launch Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes' prompts you to reboot, please do not do so.

  12. MBAM will now automatically start and you will see a message stating that you should update the program before performing a scan. As MBAM will automatically update itself after the install, you can press the OK button to close that box and you will now be at the main program as shown below.

    MalwareBytes Anti-Malware Screen

  13. On the Scanner tab, make sure the the Perform quick scan option is selected and then click on the Scan button to start scanning your computer for Windows Antivirus Pro related files.

  14. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you go and do something else and periodically check on the status of the scan. When MBAM is scanning it will look like the image below.

  15. When the scan is finished a message box will appear as shown in the image below.

    You should click on the OK button to close the message box and continue with the WindowsAntivirusPro removal process.

  16. You will now be back at the main Scanner screen. At this point you should click on the Show Results button.

  17. A screen displaying all the malware that the program found will be shown as seen in the image below. Please note that the infections found may be different than what is shown in the image.

    MalwareBytes Scan Results

    You should now click on the Remove Selected button to remove all the listed 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.

  18. When MBAM has finished removing the malware, it will open the scan log and display it in Notepad. Review the log as desired, and then close the Notepad window.

  19. You can now exit the MBAM program.

Your computer should now be free of the WindowsAntivirusPro 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.
