Almost every night my computer suddenly becomes real slow. I'm finally
catching on to what it is. I hit alt ctrl del and it seems MsMpEng.exe uses
upwards of 80-90% of my resources. Why so much? It boggs me down considerably
and when i try to end task, it won't let me. It's buggs the crap outta me and
is making me consider ditching it. My computer is up to date, virus and
spyware free.

Hi Steve;
I took a look at something similar the other day in which it appeared that
my Defender had it's affinity set by default to just one of my virtual CPUs
on the Pentium 4 chip. Is that Athlon 2800+ a multiprocessor chip? Do you
get two CPU processor Usage History graphs in Task Manager if you can
choose the 2 CPU view? Doing a FULL Defender scan pretty much pegged out
one of my processors... but there was all of the remaining CPU available,
so I hardly noticed the hit. Anyway I'm wondering if Defender isn't
optimized for a multiprocessor environment... which of course needs to be
enabled in the bios if it's available to you. I'm pretty clueless when it
comes to the AMD chips... but would really like to hear back from you on
this. That's gotta be a pretty fast machine right? Is it optimized for
gaming rather than multitasking?

Another thing you need to know is that the recommendation (Msft) is to do a
scheduled quick scan, and only repeat with a full scan if something shows
up. The quickie takes like 5 minutes and subjectively uses even less
resources during that interval than a full scan would.

I was having the same problem, which also included defender making a system
restore point every 10 minutes!! I had to uninstall it and now everything is
fine.
 
Yeah, i also have days where it restores itself like 4 or 5 times. and then
it will skip a day and then repeat.
