The error occurs when you click on the application icon to open it, but instead of launching, you see a blue rotating circle followed by the error message. The error prevents the user from launching Malwarebytes at all and can be quite infuriating if you immediately need to scan your computer for Malware.

As the message implies, the error is primarily caused due to some problems with the Malwarebytes service.

Method 2: Add Malwarebytes to your Antivirus Exception list

Many users couple their existing antivirus programs with Malwarebytes for an additional layer of security. While this may seem like a good strategy on paper, there are a few things that can go wrong. First up, Antivirus and Antimalware programs are infamous for hogging up a lot of resources (memory) and having two of them active at the same time can lead to some serious performance problems. Second, since these applications perform similar tasks, a conflict may arise, causing issues in their operation.

Malwarebytes has been proclaimed to play well with other Antivirus programs, but users continue to report errors due to a conflict between the two. The issues have been predominantly reported by F-Secure users, an antivirus program.

You can resolve this conflict by simply adding Malwarebytes to the exclusion or exception list of your antivirus. The procedure to add an application to the exception list is unique to each antivirus software and can be found by performing a simple google search. You can also choose to temporarily disable the antivirus <span data-preserver-spaces=”true”>when you need to perform a malware scan.
