Service taking too much resources

[sikuneh]

I think I may have a virus, or the remnants of a virus because my process "svchost.exe" is taking upwards of 100,000 k and if I'm not mistaken, that is a bit too much.

Can someone tell me how to find which service is taking up so much memory and fix this?

Yep, sounds a virus. Symptoms would indicate it's the "Blaster" virus.

If that link above does not work then you may have the conficker virus as well.

"Blaster worm not found on your system"

Anything else it could be?

Run MalwareBytes and SUPERAntiSpyware just for safe measure to make sure things are clean. If svchost.exe (Take note of the name! Malware likes to disguise itself as scvhost.exe or svchast.exe) is only using 100% CPU for a few minutes, it's possible Microsoft Update is to blame, which I've seen on some PCs.

I'm afraid neither of those worked. Both said they found nothing and svchost is still 100,000+k.

Any other ideas?

Go to Start > run or Start > Search bar (if running Windows Vista/7) and type in services.msc . Once there, shut down the Automatic Updates service. See if the svchost.exe memory usage drops.

The automatic update for windows? 'Cuz that didn't change it.

Ok, I looked into it a little more using Process Explorer and found something strange.

My process svchost.exe is taking up [at the moment] 144k but all the underlying services add up to no more than 15k. Can anyone explain?

Post up what you see for Process Explorer including any details it gives about the affected svchost.exe process. Screenshots are appreciated.

Is this enough information?
