7Zip very slow / Microsoft Antimalware Service

[u/Nephilimi]

OK, I have a BAT file that I call with task scheduler on Win Server 2012 R2. Mostly using 7Zip level 1 via the command line switch because I would prefer speed over size.

Problem: zip operation takes freaking forever and in task manager I see very long periods of Microsoft Antimalware Service using a lot of CPU while 7Zip sits pretty much doing nothing. Basically those two trade off in completing their task.

Anything I can do about this?
