Windows 10: Anitmalware Service Executable

So this is really bogging down my PC to the point it is barely useable. This has not been an issue in the past but I can’t get rid of this process. I’ve disabled in the regedit, changed policies/group policies, manually scheduled scans - literally everything I can find online but this POS is still showing up in task manager using 50%+ of my memory. Can anyone help me with this?

Anitmalware Service Executable

I have recently been plagued with frequent intermittent slowdowns on an old home-built desktop. It might take the form of a delay in opening a program or copying text from Word (MS365) or pasting some text or even selecting something onscreen. Whatever request
I've asked the computer to do (see above) will eventually take place but it might be many seconds (less than a minute) before that happens. When I see that there appears to be no response to the task I can go to the taskbar and summon Task Manager.
As soon as TM comes up (usually immediately) I can see that Windows Defender Smart Screen or
Anitmalware Service Executable (MsMpEng.exe, the worst offender,) Power usage trend is "Very High". As soon as the "Very High" condition changes to "Very Low", things start moving again.

A suggestion found online said to run taskschd.msc and step down to "Windows Defender" and change the scheduling to something that would prevent that program from running while the computer was being used. I set it to refrain from running until the computer
was idle for 1 hour. This seemed to help a great deal. Of course, I have to do this every time I go to use the computer.

My question then is why is this happening now when I was never aware of it happening in the past? I am running Version 1903 (OS Build 18362.900). Updates are set to automatic and the computer is always on.

How do I turn off "Antimalware Service Executable"?

Probably a Scheduled scan is a reason why it is taking up so much resoruces. GR
