I'm using Windows XP SP2 and since a few days when I log it'a very slow. I opened task manager and iexplore.exe is using 98% and more of the cpu.I have to do an END TASK on it. Any ideas what's the cause? I have Xsoftspy, spyhunter, spybot, MS anti-spam, Norton Anti-virus and my firewall is active. I have also run hijackthis and registryfix... thanks for your help

run those programs in safe mode.
also adware and spybot search and destroy (do update there definitons files)
do a repair of IE.

and use spyblaster to protect you for future infections, http://tinyurl.com/38j5m

open regedit:start , rub regedit.
navigate to hkey_lomachine\software and delete all unknow entries
also navigate to
hkey_local nachine\software\microsoft\windows\current version\run (and run once) and delete unknown entries at the right hand side pane.

Consider using Mozilla Firfox (www.mozilla.org) they are less prone to IE explotations.

it does sound like spyware even tho you have thought of that. does it work ok for a while after you scan? does the scan find much? you are turning off system restore before scanning, yes? you are scanning in all the profiles on the system, yes? delete temporary internet files and see if anymore windows updates are available and i wll look in support.microsoft.com because this sounds familiar...

Hi

Are you saying that I.E. is using 98% of the CPU and that the program has not been started? You also say you have 'scan all profile' - singular. Have you scanned all profileS?

Also, although it may in fact be spyware that is causing your system to slow down, it may not be down to I.E. Which programs are using the largest amount of memory when you open Task Manager?

I have background processes running on my XP Pro machine that use 99% of CPU, and they do not slow the machine down. Also, how is your virtual memory setup? In fact, how much memory is installed in your machine? Can you post your machine specs?

How many background processes are running?

Give us this info and we can troubleshoot your problem a litle more easily.

Hi

As you have run spyware scans and virus checks in Safe Mode with System Restore turned off, have you also tried restoring your system to a time before the slow down began?

Also, have you just installed a new application or reconfigured any of your applications to automatically update every time the computer starts up?

If that is not the case, have a look at this article and the section about winsock:

Maybe rebuilding your winsock may help.

Good luck

For an unknown reason, can't boot in safe mode. I had installed a new dvd burner with soft. I have remove the hardware + soft, same result... It's looking like a re-install :-(

Hi again

Have you tried uninstalling and reinstalling I.E.? Also, check your core system files are intact by clicking Start>Run and typing

sfc /scannow

then click OK. If you still have problems try repairing your XP installation.

Have you also checked the Browser Helper Objects to make sure nothing is there that should not be? You can view these by opening I.E. properties and clicking the Programs tab and clicking the Manage Add-ons button. Disable anything you are not sure of.

Good luck
