Module Core Service high cpu and ram usage


Not sure if this is related to the McAfee Management Service host - VERY HIGH CPU USAGE issue, hence posting in a new thread.

So, today McAfee started acting out all weird. Randomly when playing games my fps would drop to 1, and the whole game would freeze/lag for a few seconds before returning to normal. After a while I managed to figure out that McAfee's Module Core Service was the culprit -- it randomly jumps up to 20-30% CPU usage (which causes the whole laptop to lag to the point where I can't even move the mouse), while also maintaining a consistent 2-3GB of ram usage (see https://imgur.com/a/9Yj9M)!

What is Module Core Service doing that can cause it to freeze the whole system like this? And is there anything I can do to prevent this?

I have tested restarting, with no results. McAfee Virtual Technician or whatever it is called found no problems. I'm running Win 10 x64, with McAfee LiveSafe 16.0 R8.
