Ok so my computer is acting up , at first i thought it was a ram issue , but when i am only use 1 gb of ram ( i have 2 gb) my cpu usage goes to 100 then drops to 30 then back to 60 and so on , even on start up it goes to around 50% without anything opened. So i tick the show all process on my task manger and i see alot of svchost , more than 6 running, should i be worried, i heard some of them could be a virus and i also MsMpeng.exe running and it uses 50,000 usage, it uses more memory than google chrome.
So my question is how do i fix this ??? both svchost and MsMpeng.exe worries me , iknow svchost is safe but it also good be a virus.
Any help on these would be greatly appreciated.
Im running windows 7 32 bit.
