Error loading C:\Windows\System32\NvCpl.dll

My wife has a Dell Dimension 4100 running with Windows ME. Today, for no apparent reason, when she boots-up, she see a box entitle Rundll that gives the error message, "Error loading C:\Windows\System32\NvCpl.dll. The sytem cannot find the file specified." This problem seems to have coincided with some problems she's having with Norton SystemWorks 2003, like not being able to enable the Norton Anti-Virus and Personal Firewall features; these problems also just started. Anyway, does anyone know what the Windows error message means, how to repair the error, and whether the error has anything to do with the Norton applications (I'm uninstalling and reinstall the latter, by the way).

Yeah it does. Unisalling and reintalling Norton usuall fixes this.

Good call Steve it does come across that it may be the YAHA worm

Here is a link on how to remove it. This is pretty detailed so pay close attention and do it the way it is outlined.

Cannot start Norton AntiVirus 2003 after installation

Situation:
After installing Norton AntiVirus 2003 (NAV) or Norton AntiVirus 2003 Professional Edition (NAV Pro) and restarting the computer, NAV or NAV Pro will not start. The program will not start when you double-click the NAV or NAV Pro desktop icon or the NAV or NAV Pro Auto-Protect icon in the system tray. It will also not start when you try to start NAV or NAV Pro from the Start, Program menu.

I uninstalled and then reinstalled Norton SystemWorks, and now both Norton AntiVirus and Personal Firewall are working again with no apparent problems. I also scanned the hard drive for viruses using the latest Norton virus definitions, and none were reported. In spite of these actions, the original Windows error message still appears at boot-up, but all the applications on the computer seem to be working --any further ideas about this persistent though apparently benign error message?
that is not for Norton, it is for Nvidia.
first search your drive for the file see if it's there (or if it is else where, and if it is in the wrong place move it to c:\windows\system32)
try reinstalling the drivers for it

Yes, installing the latest NVIDIA drivers did the trick--the error message is gone, and the computer's graphic card is updated. Thank you.
