What Is Antimalware Service Executable Why Is It Consuming High Cpu Try adding antimalware service executable (msmpeng.exe) to exclusion list, see if it helps: open microsoft windows defender. click on virus & threat protection > virus & threat protection settings. locate 'exclusions' and click add or remove exclusions. hit add an exclusion and select process in drop down. 7. add msmpeng.exe to exclusion list. what happens is that when scanning for malware, antimalware service executable also scans its folder where it is saved. this may again create a loop of sorts leading to high cpu and ram usage. adding the associated process to the exclusion list will prevent that.
