I had the same problem.

I ran a search for "svchost.exe" only found the "legit" version in the Windows/system32 forlder.

I notices something else - though. When I terminated the process that was hogging up my CPU, my Auto Updater icon in the task menu was gone.

When I went to Windows Update website and had it search for updates - guess what? The darn svchost process came back with a vengence.

My advice - disable the Auto Update service and/or terminate the svchost.exe process when it acts up (be careful about this, though, you might shut down your computer).

Be sure to manually check for updates (go get coffee or lunch or something until its done).

My computer is running like new again.

Hello landa321. Sorry we didn't continue our troubleshooting. :help: Kinda lost this thread :whistling:

Please download filemon. After downloading, unzip it to your desktop.

Before we get started, I want you to be familiar with the Capture button so you can find it quickly when we do this. Open Filemon. Note the button at the top that looks like a magnifying glass. Pressing that button will stop Filemon from recording (capturing) the activity of your computer. That is the button you will be pressing when I say to.

Now exit out of Filemon. Exit all non-essential programs (the ones in the taskbar next to the clock. Do this by right-clicking on them and selecting exit or close.) Now we will use Filemon.

Now, open Filemon and then immediately open one of the programs that are giving you the 100% usage problem (unless it is occurning all the time, then you won't have to open a program :blink: ). Let the computer sit for about 30 seconds. Return to Filemon (if it is not visible) and click on the magnifying glass button at the top. Now click on File > Save as... and save the log to your desktop. Attach that log to your reply to me.

NOTE: The log will be EXTREMELY long. So please attach it rather than post it out. If necessary, you may even have to compress it by putting it a zipped (compressed) folder.

I don't think that attachment worked. Here is a zipped version.

It looks like a problem with Internet Explorer, and possibly some other things.

Did you follow my suggestion in my previous post...the one about downloading CCleaner, how to set it up, and then running it?

From the log, it looks like it might be an internet explorer issue.

A number of XP users have reported situations with Internet Explorer 6 becoming corrupted and reporting a number of different errors. While there is certainly no guarantee, the two procedures listed below have restored functionality to IE6 for many users experiencing problems.

Note: Both methods listed require that the Microsoft Windows XP CD-ROM be available.

Method 1: Microsoft Internet Explorer 6.x Repair for Windows XP

From the Start menu, select Run.
In the Open field, type sfc /scannow (Note: There is a space between sfc and /scannow)
Select the OK button.
Follow the prompts throughout the System File Checker process.
Reboot the computer when System File Checker completes.

Method 2: Microsoft Internet Explorer 6.x Repair for Windows XP

From the Start menu, select Search, select All Files and Folders.
Select More Advanced Options and place a checkmark beside Search Hidden Files and Folders option.
Ensure that Search System Folders and Search Subfolders are also checked.
In the All or Part of the File Name box, type ie.inf
In the Look In drop-down menu, select C: or the letter of the hard drive that contains the Windows folder.
Click the Search button.
In the search results pane, find the ie.inf file located in Windows\Inf folder.
Right click the ie.inf file and click Install on the context menu.
Reboot the computer when the file copy process is complete.

Then you might have an infection or a problematic program. Let's find out.

Please download and run hijackthis Do a scan and then save a log. Take the log and ATTACH IT (do not post) to your next post. In order to attach it, you will either need to change the .log extension to .txt, or you will have to put the log into a compressed (zipped) folder.

We do not like to post hijackthis logs in sections other than the malware forum as we do not want to encourage people to post malware issues in this forum.

I am not looking for malware. I am looking for what programs or combinations of programs might cause this behavior. If I notice any malware, I will redirect you to the malware forum.

Sorry for the delay, I've had a busy weekend.

As far as I can tell, there is nothing in the hijackthis log that would cause that problem. Let's see what is exactly causing the CPU usage.

Download Process Explorer from Sysinternals
http://www.sysintern...ssexplorer.html

Extract and run it. Go to VIEW > SHOW Fractional CPU usage
Make sure it is checked.

Look in the CPU column and relate what is consuming your CPU (of course you will have to do then when your CPU is at 100%)

If you can, a screencapture would be useful. You can take a screenshot by pressing Print Screen/SysRq on your keyboard. Open Paint and paste. Save the screenshot as a JPEG and post it in a reply to me.

Interesting. It is svchost.exe, which is a system process, that is causing the CPU usage. Before I go and research what the probable causes are, let's see what Filmon tells me that it is accessing.

Please download filemon. After downloading, unzip it to your desktop.

Before we get started, I want you to be familiar with the Capture button so you can find it quickly when we do this. Open Filemon. Note the button at the top that looks like a magnifying glass. Pressing that button will stop Filemon from recording (capturing) the activity of your computer. That is the button you will be pressing when I say to.

Let the computer sit for about 30 seconds. Return to Filemon (if it is not visible) and click on the magnifying glass button at the top. Now click on File > Save as... and save the log to your desktop. Attach that log to your reply to me.
