Re: Svchost.exe using 50% of cpu

Pardon me while I go stick a couple of pins in my voodoo doll labeled
"Hewlett Packard." The mouse hover trick discloses that this instance is
doing just one thing: HP NETWORK DEVICES SUPPORT.

Key fact here: we recently bought an HP Photosmart C7280 all-in-one printer,
at least partly so we could have a networked printer. Guess it's time to go
talk to HP about why their device driver upgrade is eating my CPU. Must be a
recent change because we've had the thing for a month or so and I only
noticed this yesterday.

I've seen several threads on cases where SVCHOST.EXE was using
100% of CPU. Has anyone see it use 50% of CPU?? I have a WinXP
Pro system, updated using automatic Windows Update, running
ZoneAlarm Internet Security Suite which checks for both viruses
and spyware weekly. Earlier this week I also updated SpyBot and
LavaSoft AdAware Personal, and ran both of them. I'm behind a NAT
router.

Yesterday I noticed that 1 of my multiple SVCHOST.EXE processes
was using 50% of CPU - I'm sensitive to CPU because I run BOINC
for Rosetta@home and I expect BOINC to be using 95% of CPU.

It's still doing this today, and I checked it during boot before
Rosetta started, and it was using 50% CPU then when it had no
competition. This is forcing Rosetta down to 45-50% of CPU and
limiting the work I can do for them. Following a suggestion here,
I downloaded and ran ProcessExplorer, but it just says that copy
is:

SVCHOST.EXE SVCHOST.EXE 328 50.00 Generic Host
Process for Win32 Services Microsoft Corporation

Can somebody help here?? I'm hoping I don't have a virus.


There can be several "svchost.exe" programs running. In process
Explorer, hover your cursor over the svchost.exe that is consuming the
CPU. A pop-up window will list the services connected to that item.
Then,
start->run->services.msc
and find the service(s) listed and try to stop them one-by-one by
right-clicking on them and selecting "stop". It shouldn't take too
long to find the one using the resources.

HTH,
John
