Every day for the first 8 hours or so, my computer is unusable due to MsMpEng.exe
taking 100% CPU while scanning my file systems for viruses (I think). I’ve already excluded a whole bunch of folders. Weird thing is that when I go to Settings
and look at Virus and Threat protection
, under Current Threats
, it says Last Scan: today, 04:30, lasted 2h41m
. Yet, here I am at 11:45 and MsMpEng
is still pegging all four cores. ProcMon
indicates that it is reading the filesystem a lot….

One site I looked at suggested setting Affinity
for MsMpEng
, but I get Access Denied
, even from an elevated Process Explorer
.
Is there anything else I can try?
