How to remove VirusLocker (Removal Instructions)

What these programs do: VirusLocker is a rogue anti-spyware that masquerades as a legitimate program but in reality uses fake and exaggerated security alerts as a method into scaring you into purchasing the full version of the software. VirusLocker is installed on to your computer without your permission through the use of Trojans that masquerade as video or audio codecs. Once the program is installed, it will automatically launch and do a scan on your computer. Regardless of what it finds, it is advised that you do not purchase this software. Some of the Trojans installed with VirusLocker will also display fake security alerts in your Windows taskbar stating that there is a security problem. These alerts are fake as well and should be ignored. An image of this type of alert and of VirusLocker can be found below.

Manual Removal Instructions for VirusLocker:

These steps may appear to be long and daunting. They are, though, quite easy to do and consist of so many steps only because I have written them in an extremely detailed manner.
  1. Print out these instructions as we will need to close every window that is open later in the fix.

  2. Download SmitfraudFix.exe from here and save it to your desktop:

    SmitFraudFix.exe

    Confirm that the file SmitfraudFix.exe now resides on your desktop, but do not double-click on the icon as of yet. We will use it in later steps. The icon will look like the one below:



  3. Next, please reboot your computer into Safe Mode by doing the following:

    1. Restart your computer

    2. After hearing your computer beep once during startup, but before the Windows icon appears, press F8.

    3. Instead of Windows loading as normal, a menu should appear

    4. Select the first option, to run Windows in Safe Mode.

    5. When you are at the logon prompt, log in as the same user which you had done the previous steps.

  4. When your computer has started in safe mode and you see the desktop, click on the Start Menu button.

  5. Click on the Control Panel option.

  6. Double-click on the Add or Remove Programs icon.

  7. Find the entry for VirusLocker 3.1 and double-click on it to uninstall if found. Follow the prompts to uninstall the program, but do not allow it to reboot the computer if it asks.

  9. Delete the following files and folders (Do not be concerned if this folder does not exist):

    C:\Program Files\VirusLocker\
  10. Close all open Windows.

  11. Now, double-click on the SmitFraudfix icon that should be residing on your desktop.The icon will look like the one below:

    This program will remove all Temp, Temporary Internet Files, and other files that may be leftover files from this infection. This process can take up to a few hours depending on your computer, so please be patient. When it is complete, it will close automatically and you will should continue with step 25.

  16. When Disk Cleanup is finished, you will be presented with an option asking Do you want to clean the registry ? (y/n). At this screen you should press the Y button on your keyboard and then press the enter key.
  17. When this last routine is finished, you will be presented with a red screen stating Computer will reboot now. Close all applications. You should now press the spacebar on your computer. A counter will appear stating that the computer will reboot in 15 seconds. Do not cancel this countdown and allow your computer to reboot.
  18. Once the computer has rebooted, you will be presented with a Notepad screen containing a log of all the files removed from your computer. Examine this log to see what files were found, and when you are done, close the Notepad screen.
  19. We next perform an online scan with Panda to find any possible inactive remnants from this infection: Panda Online

    1. Once you are on the Panda site click the Scan your PC button

    2. A new window will open...click the Check Now button

    3. Enter your Country

    4. Enter your State/Province

    9. It will start downloading the files it requires for the scan (Note: It may take a few minutes)

    10. When download is complete, click on Local Disks to start the scan

  20. When the online scan has been completed, let it remove what it finds, and then you can close Internet Explorer.
Your computer should now be free of the VirusLocker infection. If you are still having problems with your computer after completing these instructions, then please follow the steps outlined in the topic linked below:
