I’m running a Threat scan right now and Task Manager shows Mbam to be using 100% CPU, but it doesn’t seem to be interfering with running Waterfox and me typing this message. I wrote a comment before updating it so decided to delete it and run the update first. So, if you dropped the program because of stability issues, you may want to give it another try to see if those are resolved for you as well especially with the crash related fixes in the three releases of 2018. The program was responsive both when it ran in the background but also when it was scanning the system or performing other operations. Stability-wise, progress appears to have been made.

Some users reported abnormally high memory usage and this may have fixed the issue.Â The two updates that Malwarebytes released in March for the application did fix several crash and stability issues as well. The new version fixed an issue in the program's anti-ransomware module that caused high memory and CPU usage, and crashes related to the web protection module. The situation has not improved all that much unfortunately a quick Windows Task Manager check revealed that the Malwarebyte's processes used roughly 280 Megabytes on the test system with the interface displayed and about 220 Megabytes with the interface not displayed.

One of the main issues that I had with Malwarebytes 3 was the application's high memory use.
