Long time reader and admirer of the articles - especially on Windows 8.
But now I turn the fate of my sanity to you guys.
A while back I switched from my former favorite AVG Free to my new preference; Microsoft's MS Security Essentials (I believe it was based on an article I read here..?)
I had it running alongside MalwareBytes' Antimalware Free edition, and they seemed to go along nicely, not clashing at any point or anything happening with them.
Then about two months ago, at times my CPU would be dragged upwards of 90-100% and just stay there. In task manager, the MSE process MsMpEng.exe would draw everything between 40% and 90% of the CPU.
I then uninstalled MalwareBytes, and used the cleaner provided by MalwareBytes to remove every trace of it, but still the process at seemingly random times 'steals' my CPU.
I'll appreciate any input and idea. When I get home I'll post a HijackThis-report.
