This one system starting using 100% processor for svhost.exe when the system
boots up a few days ago, we go to task manager see the svhost.exe that is
using all of the processor, end that task, and the user is back in business.

I saw some information on the net that is may be a virus --- I boot the
machine up in safe mode, with system restore off, ran a full scan and no
threats, also ran a full scan while not in safe mode and still all clear.
There are a lot of ideas on the net as to how to fix this ---- just wondering
if anyone ran into this problem and if successfully resolved. Any assistance
would be appreciated.

Thanks,

I had the EXACT same problem with my WinXP system, got no help here -
only told it was likely a malware, or such, infection, jumped through
many,many hoops looking and searching for an infection, and found
none, but problem continued.

The Windows98 group helped me by telling me it had something to do
with the system legitmately looking everywhere for a driver, or
something. After I disabled the software that asked for that search,
all the svchost.exe CPU hogging problems magically went away!

interesting... care to share how you figured out which software was
doing all the calling?
