Malwarebytes, a popular Windows antivirus program that is one of the best anti-malware antivirus programs on the market. However, the CPU problem of the Malwarebytes service can sometimes occur under Windows, and this problem makes it difficult to use the full suite. As long as Malwarebytes is running on your computer, this problem persists. There are several methods that can help you solve the problem with the high CPU performance of the Malwarebytes service, and you can try them.
As a general rule, the more antimalware/antivirus protection you add to a PC, the more CPU processing is needed to handle potential “threats”, resulting in a high CPU overload (up to 25% or more!) and a much slower system. This is especially true for older and slower hardware, which may not be the case if you have a state-of-the-art PC.
Causes of the Malwarebytes Service High CPU Problem
It is difficult to find the direct cause that causes the Malwarebytes service to consume too much CPU power. Malwarebytes’ official answer is to simply reinstall and install the latest version, which has actually worked for many users. This means that it was a bug in the version of Malwarebytes you installed that could be fixed in the next version.
If the next version is not available, the only way to check if the other antivirus program you have installed is problematic is to uninstall it. If this is not the case, you can only stop the service until a patch is published!
