For that, you can open the Task Manager on your computer, find out the Malwarebytes processes one after one, and click the End process button.
2] Disable auto malware quarantine
Malwarebytes automatically quarantines malware when detected on your computer. It is the standard behavior of anti-malware software, and this security tool follows the same method. However, the same feature can cause high CPU and Memory usage on your computer, making it slower than usual. Therefore, do the following:
Open Malwarebytes on your computer.Click the settings gear icon visible on the top-right side.Switch to the Security tab.Toggle the Automatic quarantine button.
Disabling this option might solve the problem, but it makes your computer partially vulnerable since you need to do the quarantine job manually.

Now follow the first solution on this list to close all the processes of Malwarebytes and restart it.
4] Increase Update threat intelligence time
By default, Malwarebytes searches for new threat intelligence updates every hour. For that, it requires some amount of CPU resources and an internet connection on your computer. If you increase the interval, it won’t search for the update as frequently as the default setting. For your information, you can set it anything from 1 minute to 14 days. To do that, follow these steps. Now, restart Malwarebytes and check if the problem resolves or not.
5] Search for updates
Malwarebytes repeatedly acknowledged the high CPU usage problem in the past. They released minor updates to fix the issue earlier.

However, you should remove all the leftovers before reinstalling the app. Although Malwarebytes Support Tool may help you in this case, it is recommended to use third-party software uninstaller, such as Revo Uninstaller, CCleaner, etc. Following that, you can download the app from the official website and activate it with your product key.
