Why is Service Host using so much CPU time?

wompai
Ey guys,

I noticed that my computer (running Win7) reacted very slowly. I could see that my CPU was constantly running at 60-70%. So I checked with Process Explorer which process was causing it to slow down. It appeared that a copy of Svchost.exe (or Service Host) was using a lot of CPU performance and I checked what services where hosted by Svchost. It was hosting Windows Defender... Is Windows Defender the cause of my problems? Can I shut this process down?

    That would take a certain amount of processor time.

    Also, the same program could be updating it's virus signature.

    If Windows Defender is your only anti-malware app, your issue may be the symptom of a malware infection. WD is a free Microsoft app that is typically ranked #11 in top-ten AV software reviews.

    If WD is not your only AV, then it may be conflicting with your main application, and it should be disabled and installed.

    It can be that it's updating or checking things, but that's unnecessary because I have Avast! installed and that one is working perfectly... So is it safe to just kill the process?

    you can kill any process you want without harming your machine.

    some processes however, won't allow to be killed and there is one that will simply shut down the pc.

    so go ahead and shut down which ever process you think is problematic and see if it improves your system performance.

    later, you can then analyze that process and determine if it is actually needed.

    incidentally, there is a freeware called jet boost and jet clean. one of them clears memory out of unneeded processes. works pretty good on vista but haven't tried it out on win7.
