37How To Fix Antimalware Service Executable High Memory / CPU Usage on Windows 10/11.
Antimalware Service Executable is the name of the process MsMpEng (MsMpEng.exe) used by the Windows Defender program. The service associated with this program is the Windows Defender Service. The two most common reason for it to be consuming high CPU usage is the real-time feature which is constantly scanning files, connections and other related applications in real-time, which is what it is supposed to be doing (Protect In Real Time).
The second is the Full Scan feature which may be scanning all files, when the computer either wakes up from sleep or when it is connected to a network, or if it is scheduled to run daily. The bit to understand here is that when it is doing a complete scan, your system will experience frequent lagging, hanging and delayed access/response from your input/interactions with the system, because the CPU is Hijacked by Defender. Don’t be afraid or lose patience here, instead let it run and scan, wait a few minutes and if there are lots of files, etc, then it may even take a few hours, so let it runs and finish what it is doing for the sake of your protection, once it has completed, it will release the CPU and the USAGE will drop down to its normal.
Windows Defender uses the Antimalware Service Executable or MsMpEng (MsMpEng.exe) process to execute its functions. However, a number of Windows users have noted that the Antimalware Service Executable (MsMpEng) sometimes shows high CPU usage.
