This is a persistent problem I have had for many months. I have McAfee
running all the time; I've run scans, I've run Adware; I've run chkdsk; I
even backed off SP3 and reinstalled it - all to no avail. The error dumps
fill up my HD requiring me to delete the files periodically. Also, explre
runs VERY slow when I open a folder for the first time. I have an ACER
Aspire 5000 notebook w/ AMD Turion and 1.2GB memory. I have a ton of error
msgs in event viewer. It appears that a new one is created even when I'mnot
doing anything. Below is a sample. Please help.

The Generic Host Service (svchost) is a host for other services. You
want to find out which underlying service is causing the problem.

Process Explorer will show you which processes are being hosted by
svchost. This is your starting point towards identifying which process
causes the problem. (My guess is malware.)

Get Process Explorer here:

Nass - Thank you very much for your help! I did everything that both you
and Leonard suggested, but I still have the problem. I suspect that malware
may not be causing my problem. Yes, I'm getting the DEP and Win32 msgs every
time I boot the system. I noticed that it only occurs if a svchost.exe dump
file exists. I can usually avoid these msgs if I delete those files before I
re-boot. I monitor that directory while I'm running and I can see when a dump
file appears. It happens consistently when I launch Explore or IE. A
potential memory problem never occured to me. I'm not aware of any
diagnostic tool that came with my system. Can you recommend one that won't
require creation of a boot disk?

I'm sending you the Hijackthis log file.

Hi Tom,
That make things easy a little bit!
The DEP can occur if you installed a new security software or an Unsigneed
driver like Scanner, Printer or a general driver for a new hardware.

We can tell to turn off the DEP message but my worries is it can be more
than that and we just killing the system by shutting/disabling the DEP!

Let me know if you installed new hardware/updates recently and also for the
record I have found that an old security suite (the left over/behind
orphans/folders) can cause the same issue.

If you can send me the Dump file that will be great too!
