Causes of Malwarebytes Not Opening on Windows

There are several reasons for getting the “Malwarebytes won’t open” alert. The reason might be small or severe. In both cases, we need to take immediate action to have the proper security of our data. Two significant reasons for this situation can be:

Blackhat developers are becoming smarter by the day. It is possible to have malware in your system that prevents the antivirus program from starting. Malwarebytes has a mbam.exe executable file that needs to be working for launching Malwarebytes. Try renaming the mbam.exe executable file to get rid of the issue.

2. Corrupted User Account

If you are using a corrupted or faulty user account on your Windows PC, then it could be dangerous. The damaged user account can prevent many apps from launching like Malwarebytes. You can try to switch to a different user profile to solve the issue.
