svchost.exe spiking to 100% cpu
 

Hi.

I've observed over the past few days when I start my computer up from cold, that svchost.exe hogs 100% of the cpu, yesterday a reboot stopped this today it did not, I then terminated it's task from task manager and the system returned to normal.

Scans with ad-aware, spybot and AVG Free have come up with nothing, and I run Zonealarm firewall alongside.

Any pointers?

Right Zonealarm has gone, my sounds returned and computers more stable...

Lesson learned..I'll update this thread with anymore problems :dozey:

I had this issue on my laptop thought it was spyware too but it wasn't it was cr**py windows itself doing it from time to time.... Machine ground to a halt.

Thats why I got fed up and installed linux :)

Use Tasklist /SVC to find attached processes link to the service.
link about tasklist
or try using HijackThis to check whats going on

Also, Process Explorer from Sysinternals will give you a lot more info about it than the bog-standard Windows Task Manager does.

I know i've said it before, but ZA is crap. Try Kerio or Comodo.

Well since Zonealarm has gone alot of my recenty wobbly pc troubles has gone.

I thought for a while my new Asus A8n-32Sli Deluxe mobo was acting the goat...nice to know it wasn't.

I'll go grab Sygate firewall :D done me well for the past few months before I upgraded to this mobo, what was I thinking with Zonealarm!

i had a similar problem recently. my av software kept complaining about a file in the windows directory xml something or other.

I reinstalled windows from my ghost DVD image and everything was back to normal :)

It may be Windows Defender if you have that installed, are you seeing any activity from MsMpEng.exe in your processes?

If you are, it could be Windows defender.

Re: svchost.exe spiking to 100% cpu
 

I do not have Windows Defender install, only new things from Microsoft is IE7 final, and Mp11 beta 2. Since the removal of Zonealarm the problems gone away so I think that had it nailed.

Oh, hello, that was my commonality, the upgrade to Microsoft IE 7

Maybe there is a bug/virus that attacks ie7
