Antimalware Service Executable (MsMpEng.exe) cause for 100% CPU usage

[Luisvega]

Hello!

I am using Windows 10 Pro.
I recently installed Spybot Search and Destroy free edition, the on screen display shows that I am reaching 100% CPU usage.
When I open Task Manager, I found Antimalware Service Executable (MsMpEng.exe), which consumes 90-100% of memory. I used Spybot Search and even Windows Defender is available on Windows 10 but the problem is still not improving.
Need help from everyone!

Antimalware Service Executable is part of Windows Defender, Luisvega. HowtoGeek has a pretty good article about it here:

If you scroll down it has an article section called "Why Is It Using So Much CPU?" which you might like to read.
Please post back and let me know if the article helped any. :)
