How to Stop Antimalware Service Executable From Using CPU

Antimalware Service Executable, also known as MsMpEng.exe, is a crucial component of Windows Defender, the built-in antivirus program in Windows 10. While it is essential for protecting your system from malware and other threats, it can sometimes use a significant amount of CPU resources, causing your computer to slow down. Fortunately, there are a few solutions to stop Antimalware Service Executable from using excessive CPU.

1. Change Windows Defender’s scanning schedule: By default, Windows Defender scans your computer in real-time, which can consume considerable CPU resources. You can adjust the scanning schedule to occur during idle times or when you’re less likely to be using your computer.

2. Exclude certain files or folders from scanning: If you notice that specific files or folders are causing high CPU usage, you can exclude them from being scanned by Windows Defender. Open Windows Security, go to Virus & Threat Protection settings, and add the exclusions.

3. Limit CPU usage in Windows Defender settings: You can reduce the maximum amount of CPU resources that Windows Defender is allowed to use. Open Windows Security, go to App & browser control, and under the Exploit Protection settings, enable the “Reduced CPU usage” option.

4. Use a different antivirus program: If you consistently experience high CPU usage or find Windows Defender problematic, you may consider using a third-party antivirus program instead. There are many reliable options available in the market.
