100% CPU Usage at Start Up and system hanging

I am running XP. Today on start up it kept hanging and took 15 minutes to show all icons. Then when trying to open programs it did the same. Can only operate in Safe mode. Have done Trend Micro scan, Trojan Hunter and Ad Aware and it appears clean. When I check Windows Task Manager in regular mode the System Process is at 99%. In Safe Mode System Process is 0% Can anyone help?

 

disable your anti-virus program, see it that works, if so... uninstall it, reboot and reinstall it.

After doing ALL of the above if you still have a problem:

http://www.majorgeeks.com/images/grenade.gif Unzip the hijackthis.exe file to a folder you create named C:\Program Files\HJT

http://www.majorgeeks.com/images/grenade.gif Do NOT run Hijack This from the Desktop, a temp folder, or a sub-folder of C:\Documents and Settings, or choose to run it directly from the ZIP file as your backups will not be safely stored.

I also posted to the Software problem and got the answer. Thanks to Frustrated for this:

Since you have Trend-Micro I assume you have PC-cillin internet security 2005. I had the same issue starting yesterday - I assume they must have had a bad update! I found this article on their KB. Take a look:

http://kb.trendmicro.com/solutions/...olutionId=24264

Here are the details of the article in case you can't get there:

Problem: This issue has been reported mostly by users with PC-cillin Internet Security 2005 installed on a computer with Microsoft Windows XP + Service Pack 2 (SP2) operating system.

Solution: To resolve the issue:

Start the machine in safe mode:

If the computer is running, shut down Windows, and then turn off the power.

Wait 30 seconds, and then turn the computer on.

Start entering the F8 key. The Windows Advanced Options Menu appears.

Note: If the Keyboard Error message appears, restart the computer and try again.

Select the Safe mode option.

Press Enter. The computer will then begin to start in Safe mode.

Go to the c:\program files\trend micro\Internet Security 2005 directory then delete lpt$vpn.593 and/or lpt$vpn.594.

Restart the computer. After restarting, open PC-cillin and perform an update by clicking Update Components.

In case you are unable to update properly, a manual update can be performed. Refer to Solution 21946.

Hope this helps!
