Since the release of Windows 10 2004, users have been reporting performance issues and crashes when Malwarebytes 4.1 is installed.
In numerous reports to the Malwarebytes support forums since Windows 10 version 2004, the May 2020 Update, was released, users are reporting many problems with MBAM 4.1 installed.
These issues range from random freezes, general slowness, video stuttering, blue screen of death crashes (BSOD), or Windows 10 becoming unresponsive.
Some users have reported being able to resolve the issue when disabling Malwarebytes’ ‘Ransomware Protection’ feature in Malwarebytes.
Malwarebytes has also released a Windows Beta version 188.8.131.52 in early June that appears to resolve this issue.
Users can install the Beta version by going into Settings > General and enabling the ‘Beta updates‘ setting.
Once this setting is enabled, users need to check for new updates to install the latest version and its components package.
If this does not resolve your issue, you should open a support topic in the Malwarebytes forums to receive additional help.
