How can I stop Mcshield.exe high CPU usage?
1. Update PC
The first thing to do if the Mcshield.exe process uses a high percentage of your CPU is to update your PC. This is because your present PC version does not have what it takes to handle the security feature at the time. Hence the need to update your system to the latest version.
2. Disable the anti-spam feature
For some reason, users have found the anti-spam feature of McAfee antivirus to increase the Mcshield.exe CPU usage. Disabling this feature almost half the resource usage process. This shouldn’t be a problem, as most email clients have built-in anti-spam features already. Also, if you are using the latest version of McAfee products, you will not find this feature there, as it has been removed. So, move to the next fix instead.
3. Remove conflicting apps
If you use other antiviruses or security software with McAfee, you might experience the Mcshield.exe high CPU usage issue. So, you need to remove this software to restore normalcy on your PC. To be sure that you have removed all components of the app, we recommend using dedicated uninstaller software in CCleaner to uninstall it. This excellent tool removes even the most hidden element of any software and eliminates any leftover files that can cause issues. Also, CCleaner is a PC cleaner that can remove junk files. This is important to reduce your CPU and memory usage to a minimum. We have reached the end of this guide on the Mcshield.exe high CPU usage issue. If you still can’t fix the problem after applying the solutions above, we will recommend switching to one of the best antiviruses for Windows PC.
