But before uninstalling Malwarebytes, we need to get your ID and Key codes to activate the software the next time you install it.

To get your activation information, you need to follow these steps:

  1. Open the Registry Editor. You can do that running the command regedit in the Run window (Win + R)
  2. Once there, you need to navigate to the following path depending on your architecture:
    HKEY_LOCAL_MACHINE\SOFTWARE\Malwarebytes' Anti-Malware
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Malwarebytes' Anti-Malware
  3. There, you need to check the entires ID and KEY and take note of those numbers to be able to activate your Premium version the next time

Solution 4: Add Malwarebytes to Exclusions

This message “Unable to connect the service” on Malwarebytes has been reported when you have installed another security software on your PC.

If you have installed another antivirus on your computer, maybe this program is blocking somehow the Malwarebytes core services, and that’s the reason why you can use the program as usual.

Some quick workaround is to add the Malwarebytes software to the exclusion list of your antivirus, and you can do that following the documentation of your program.

Anyway, I will leave the steps to add Malwarebytes to the exclusions list of Avast. If you have another antivirus, you can find the same settings quickly on the Settings.

  2. Click on the Menu at the top and then navigate click on the Settings button

    malwarebytes exception
  5. Finally, you can close the Avast Panel and launch Malwarebytes; hopefully this time you will able to use the antivirus without issues

Solution 5: System Restore

This is your ultimate solution if you haven’t been able to fix the problem with any of the methods above. System Restore will rollback your computer to an earlier date where Malwarebytes was working without problems, and you can try it following these steps:

  1. First, open the Control Panel
  2. There click on the section System and Security and then click on System
    system control panel
  3. In this new window, on the left side, click on System Protection
    system protection windows 10
  4. Now click on the button System Restore
    system restore
  5. In this utility, click on Next and then choose a date where Malwarebytes wasn’t showing the message “Unable to connect” and click on Next
  6. Finally, follow the System Restore tool until you ultimately restore your computer. Surely this time, Malwarebytes will be working correctly.
