hello,

regading my earlier post it is like this when i see the processes in the Task manager it shows system idle as 90% but when i go to performance it shows the CPU usage around 60-70%.
Is it ok?..

regards
Tamal

i run windows xp home edition and i have the problem that one of the svchost.exe in task manager is running at 100%cpu which is making computer slow and crash..i have run my anti virus and nothing is picked up ..despite no virus i have used the removal tools for blaster and welchia and nothing nada..what is also strange is that my norton gets edited where the automatic live update gets turned off and i have to renable it ..at times it disables it...im at the end of my tether i dont even know if this message will post...since i use xp i dont have task list and at the moment i feel very paranoid downloading anything...does this mean i have to reformat

ps forgot to mention that when i start up and check task manager i have an application called findows running in applications and when i check to see which process its running on it goes to rund32.dll file...i have no clue what findows.

I am highly suspicious of findows. Have you run any anti-spyware software lately? I can certainly recommend Spybot Search & Destroy. You might also try the Sasser removal tool (this article discusses: http://ask-leo.com/archives/000114.html ). You didn't indicate what AV software you're running (sounds like Norton, though) ... you might try one of the free ones as a second-level test: recommendations here: http://pugetsoundsoftware.com/recommend.html

Good luck!

Tamal: it does seem a little odd. In task manager when you're looking at performance, select "View" and "Kernel Times" - is the resulting bar mostly red or green? Also ... how fast and old is your machine?

hello sir,

i have a PIII 500 MHZ 192 SDRAM...with WIN XP when i do as you have said -the kernel times is mostly red.
My pC is four years old now.

Hello
just a couple of days ago, my svchost has been acting kinda weird. Only one, the "local service", is using more and more of my CPU Usage. When i first restart my computer, it's normal, but the longer it's on, the more CPU Usage it uses. I've done everything you say on this page, and nothing. I am still having the same problem. I've scanned for viruses, and i have none, my definition of viruses are always up-to-date. I have Windows XP home, and i have Norton. I've gone into "command", the pressed netstat, and i have no viruses i'm almost certain.

Hi there,

I'm running into problems similar to those described here... svchost.exe is hogging my CPU and my internet connection isn't working. I am using Windows 2000, and Ad-Aware found nothing, and Norton found nothing (though my definitions are from late April). I found that when I disabled the 'RIP Listener' service, svchost.exe stopped hogging my CPU. However, my internet connection is still gone. My two home machines connect through the same router, and my other machine (older, running Windows 98) is still working fine with no problems.

I can't check windowsupdate or anything else for updates, because my internet connection is gone on that machine.

Any suggestions to how I can get my internet connection back?

Both Gummo & Daron: do you have a firewall in place and enabled? I also keep hearing of AV software that isn't always catching the virus, so you may try another brand (a couple of free ones are listed on http://pugetsoundsoftware.com/recommend.html ). Naturally you do need to make sure your AV software has the latest virus definitions.

Good luck...

Tamal: nothing obvious comes to mind. I'm not sure why your performance measure should look different one way than another. Since you were infected with sasser, I'll point you at this article: http://ask-leo.com/archives/000114.html but it sounds like you may have already taken the steps listed there. It's worth reviewing, though.
