svchost running at 100%

[glenn]

Hi all

I have an XP home laptop sp 2 about 9 months old with svchost running at
100%

The laptop only has office 2003, QuickBooks installed along with ie7 and
kaspersky av of which nothing has changed for at least 6 months. AV scans
show nothing, hijack this shows nothing that should not be there and
ad-adwear and spybot show nothing either. When I kill the svchost the laptop
continues to run but stops services such as dhcp client, firewall,auto
updates etc. When I stop these manually whilst svchost is running at 100% it
does not make any difference.

Can anyone shed any light on this
Cheers

Glenn

From Ramesh's web site: http://windowsxp.mvps.org/svchost.htm
Also: http://support.microsoft.com/?kbid=314056

To find out more about Svchost.exe entries try Process Explorer:
http://www.microsoft.com/technet/sysinternals/SystemInformation/ProcessExplorer.mspx

Once you have Process Explorer installed and running:
In the taskbar select View and check 'Show Process Tree' and 'Show Lower
Pane' options.
(This will provide the detailed info you need)
Next click/Expand the Svchost.exe process that you are interest in.
Then highlight one of the process listed under Svchost, right click and from
the options listed select: google
This should display what out there on the web about that process.

Still another tool is What's Running

There has been a rash of this associated with the windows update service.
Here are some tips from a post by PA Bear, MVP

Try deleting the contents of this folder (or the folder itself) & reboot:

C:\WINDOWS\SoftwareDistribution\DataStore

If no joy, try deleting the contents of this folder (or the folder itself) &
reboot:

C:\WINDOWS\SoftwareDistribution

Workaround: Change the default from Microsoft Update to Windows Update: Go
to Microsoft Update > Click on Change Settings in left pane > Scroll to
bottom of page > To Stop Using Microsoft Update > Disable Microsoft Update
software and let me use Windows Update only (check).
