Antimalware Service Executableis one of the background-running services in Windows Defender.
Antimalware Service Executable is running to scan the malware and spyware when you access them. It will detect if there’s anything harmful on your PC Aside from that, it also takes a background scan of your system for any viruses or worms. Its
scanning relies heavily on your computer’s CPU, that’s why you find it’s eating the CPU usage on your Windows 10.To get this sorted, I suggest to follow the steps below:
Method 1: Change Windows Defender’s schedule
The error is mainly due to its real-time protection feature. Kindly follow the steps to change Windows Defender’s schedule to fix it.
On your keyboard, press the Windows logo key and R at the same time to invoke the
Run box. Type taskschd.msc and press Enter.
Double-click on Task Scheduler Library> Microsoft> Windows.
Double-click Windows Defenderin Windows. Then double-click Windows Defender Scheduled Scan.
Uncheck Run with highest privileges.
Uncheck all the items in the Conditionssection. Then click OK.
Method 2: Add Antimalware Service Executable to Windows Defender exclusion list
On your keyboard, press the Windows logokey and I at the same time to open the Settings window.
Click Update & security.
Click Windows Defender. Then click Add an exclusionin Exclusions.
Click Exclude a .exe, .com or .scr process
Type MsMpEng.exe. Then click OK.
Restart your PC and see if the issue persists.
