Hi everyone!

My computer sprung a memory leak on one of my svchosts, and I can't figure out how to fix it.

I'm running Win XP Pro and have already gone through two different anti-virus programs (Avira and Vipre) and two anti-malware/spyware programs (Super Antispyware and Malwarebytes) and confirmed I am definitely NOT infected with anything.

I've done some research and a lot of sites seem to point the finger at a bad Windows SP3 update, but when I attempt the patch fixes they've suggested, I receive an error stating that I've already updated beyond the patch.

The problem just really started over the past couple of days, but I can't remember doing any installations to prompt the issue.

Any suggestions?

I suggest thzt you tell us...just what you mean by 'memory leak" and what the symptoms of such might be, in your mind.

Also curious as to how you diagnosed such.

The computer starts up and acts normally, but if you watch the Task Manager, as time goes on, one of the svchost.exe files starts to creep up in how much of the memory is used until it has used nearly 100% of the CPU. It is also using an incredible amount of virtual memory.

If I end process on it, it will cause minor issues to the appearance and general use of the computer, but it seems to calm down the leak a bit for a short while.

Going to reboot now so I can get a good screenshot for you of it prior to ending process on it...

May be of some value:

Well, I rebooted and while it does not show that it using as large a percentage of CPU, the ACTUAL amount of memory being used and the virtual memory is insane.

I've attached images and you can see the offending svchost.exe at the top.


I actually downloaded process explorer earlier today in efforts to figure out what was causing the problem...

BITS
EventSystem
helpsvc
NLA
RasMan
Schedule
SENS
TapiSrv
Themes
w32time
winmgmt

I've attached an image of the services as well.

Now I'm back up to where the CPU usage percentage is going wild. :(

I've attached a new pic showing this. It's really frustrating, I can't figure out which part of the service is having issue. :( Please help?

I finally successfully booted into safe mode (it kept auto-restarting each time I tried previously) and I was able to run a fix_svchost executable file I found that referenced memory leaks due to Windows Update. It didn't seem to help, though. :(

Any other thoughts?

I'm either definitely NOT infected, or whatever it would be is hiding from the view of 5 different anti-virus and spyware clients, yet this problem continues. I really want to avoid having to re-image the system at all cost. :(
