Solved CPU usage goes to 100%, so computer slow

September 3, 2011 at 13:11:17
Specs: Windows XP
CPU usage goes straight to 100%, so my computer runs very slow, I have an old PC I admit - a Compaq Presario S5160UK and I don't know much about computers so a bit stuck as to what to do.
I've recently added 1GB of memory, which has all worked fine.

I have also run WinASO Registry Optimizer and cleaned all errors.

I basically use it for internet browsing, facebook and a few on-line games.

The highest usage seems to be svhost.exe - but I have no idea what that means I'm afraid, as I said I know nothing about computers. Any help would really be appreciated.

Many thanks

✔ Best Answer

Sounds like you're infected. Download and run this. Also run a good virus scan. Are you using a virus scanner? Then use this program to clean up the machine. It's free and works well.It's called ccleaner slim.

Thanks for replying so quickly, I've never used one of these forums before, very pleased.

I can not seem to be able to access the malware site - The only scanner I have is McAfee Security scanner - is this a vrius scanner?

I have downloaded the ccleaner and run that - it has made a big difference already - there was allsorts of rubbish to clean up.

Yes McAfee is a virus scanner. Do you have all the latest updates from Microsoft installed including service pack 3?
