Description:

Windows Defender uses the msmpeng.exe process and unfortunately the msmpeng.exe file does consume a huge amount of system resources and memory.

If your PC is running slow with Windows Defender then you may want to consider using a smaller, lightweight Antivirus and/or Anti-Malware software.

Having no AV is not an option so before you uninstall or disable Windows Defender then please have an alternative Antivirus program already lined up and purchased.

An easy way to see if you have any viruses before uninstalling the resource hog: Windows Defender, is to use the free PC Health Advisor scan with free download link on this page.
