My computer has been sporadically running REALLY slow. Like it will take 10-15 seconds just for text that I type to show up. Loading a web page will hang for quite a while, then load fine. It usually goes really slow for 1-2 minutes, then seem fine for a little while, then slow again. When it is fine, it could last 5 minutes or an hour. Nothing, that I can see anyway, is triggering it.
The cause of the issue seems to be MsMpEng.exe,(which is part of MS Security Essentials). When I pull up my resource monitor, MsMpEng.exe is consistantly at 23-30% CUP utilization. Nothing else is using anything significant. This exe is also taking up a decent amount of memory (235,116 kb). And a decent amount of disk activity (1,662,939 B/Sec).
This is a steady amount for MsMpEng. I'd understand if it were only when it running a scan or something, but that's not the case.
My Computer Specs (if you need them):
Windows 7 Ultimate (SP1) 64 bit
Processor: Intel Core i7 920 @ 2.67Ghz
Memory: 12 GIG
MS Security Essentials is my only anti-virus, ect so I'd really rather not just disable it.
