Here is the whole procedure in a few steps:

  1. Navigate to C:Program FilesMalwarebytesAnti-Malware.
  2. Right-click on mbam.exe and select Rename from the context menu.
  3. Rename mbam.exe to explore.exe and run it.

Running a clean Malwarebytes installation

Many users have said that reinstalling Malwarebytes from scratch has definitely solved their problem, and this is something you should try as the safest and longest method. However, if you have purchased the Premium version of the tool, you will need to find a way to get your ID and activation key back.

  • Type “regedit” in the search bar that you should be able to access after clicking on the Start menu or the Search button next to it. You can also use the Windows Key + R key combination, which opens the Run dialog box, where you can type “regedit” and click OK.
  • Use one of the registry locations listed below to retrieve your ID and key, depending on your PC’s architecture:
Location for Windows x86 32-Bit

HKEY_LOCAL_MACHINE\SOFTWARE\Malwarebytes' Anti-Malware

Location for Windows x64 64-Bit

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Malwarebytes' Anti-Malware
  • Once you have received your ID and key, you can proceed with the actual reinstallation. Follow the instructions carefully if you want to continue with your Premium version after uninstalling.
  • Open MBAM >> My account and click on Disable. Go to Settings >> Advanced Settings and uncheck the box next to the “Enable self-protection module” option.
  • Close MBAM and download the “mbam-clean.exe” tool from the Malwarebytes website (the download starts immediately when you click on the button). Close all open programs and temporarily disable all other security tools you have opened.


If none of this helps you, you will need additional help by going to the free MalwareBytes support forums. Register a free member account to publish the symptoms of the infection and mention the methods or tools you tried to use to solve the problem and run MalwareBytes.
