Explorer.exe using up all the cpu

[Guest]

I am having a problem with my explorer.exe using up 99% of the CPU processor
time, making my computer very, very, slow. I have tried to run the defrag,
and also the error checking. If I end this process it simply freezes up the
computer and all my icons on the desktop just disappear. Any ideas on where I
can go to get help on this one?

You are more than likley infected.

First job to do, go here.
ActiveX Spyware & Adware Scanning
http://www.spywareinfo.com/xscan.php
This scanner is an ActiveX applet. After a short delay in which your
browser downloads the control file, you will receive a "Warning
Dialogue" requesting permission for the scanner to run. Click "Yes" and
the applet will pop up and scan. You will be alerted if any spyware is
found. When a spyware or malware is found, you will be alerted and
asked if you want to remove it. If no spyware is found, the scanner
will disappear on its own.
If nothing happens, or if you are using a browser other than Internet
Explorer, click here and choose either "Open" or "Run this program from
its current location". Do not choose "Download".

Use Spybot Search & Destroy, Adware program to clean up any spyware.
Turn off unnecessary NT Services, e.g. System Restore can slow down overall performance and takes up a lot of hard disk space. Or, if not using IIS, disable Computer Browser. For more information, go for microsoft web site. Use classics Windows desktop theme. Uninstall all third-party programs, just WinXP itself. For mine, its 22 processes. How about yours?
