Recently my computer has been acting slow. I have updated
and ran norton anti-virus and it has shown no infection.
the problem is that one of the SVCHosts that are active in
the processes tab uses 100% of my processor every about 15
seconds for a few seconds.
 
In addition to Norton try running Ad-Aware and Spybot -
both can be found via Google. If those two don't find
something try this on-line trojan scan
http://www.trojanscan.com/trojanscan/scanner.htm
and if it finds something then the following - which comes

Trojans are stealthy and not always found by anti-virus
software. If you find suspicious processes running or task
manager or regedit is being killed after opening, you
might want to try one of the following tools to check for
trojans (after scanning with at least two anti-virus tools
to get rid of the easy stuff).

trojan system for Windows: http://tds.diamondcs.com.au/

Download Adaware from http://www.lavasoftusa.com/support/download/ and use it to remove parasites.

It is normal to have a number of Svchost.exe process entries appearing in Task Manager. For the process generating the high usage how is the User described? Next whilst Task Manager is showing high usage change from the Process Tab to the Application Tab. Then select each running Application in turn, right click and select "Go to Process" and see if you can identify the application causing the high usage.

Next select Start, Administrative Tools, Services. Compare the list of services with those shown as Started and for each in turn stop the service and observe the effect. If the CPU usage in Task Manager continues or something stops working restart the service. When you have found the likely cause i.e. the CPU usage stops then post details of what you have found.

Hope this helps.

Same happened to me - had a very rough 2 weeks! It is a Trojan Horse that Norton, Adaware & Spybot didn't pick up. I'm not a technie but go to Start-Run-msconfig-Services-click on heading Service to put in alphabetical order. I don't know if it can attach itself to any other but mine had attached itself to Terminal Services-if it isn't this one disable so as to isolate whatever (make sure you have Plug & Play, Remote Procedure (2 of them) & System Restore enabled at all times (4 in total). I'll elaborate how to isolate if necessary but it means rebooting each time so it is laborious. (Quick fix is to End Process of offending svchost but this will only be efficient until you reboot whenever and you have to End Process of offending svchost each time). Right click on My Computer to Manage-Services & Applications-Services-under name double click on Services-make sure offending file (in my case Terminal Services) is disabled. Reboot-open Windows Task Manager and svchost shouldn't be using cpu and CPU Usage should not hit and remain at 100%. Hope this helps. Davi
