backdoor.coreflood virus

I've got this virus that I can't get rid of. There is no access to it at all, and norton antivirus can't remove it either. Here is my HijackThis log, maybe some of you can figure this out?

Also, I'm having a problem with starting in Safe mode, F8 just doesnt work... Anything I can do to fix that?

Here's another way to get into Safe Mode:
Close all open programs.
Click Start, and then click Run; the Run dialog box will appear.
Type msconfig and then click OK.
The System Configuration Utility will appear.
Click on the BOOT.INI tab.
Check the "/SAFEBOOT" option, and then click OK.
You then see the prompt to restart the computer, click Restart.
The computer will then restart in Safe Mode.
Another box will open asking if you want to run in Safe Mode; click Yes.

Thanks, I downloaded msconfig, and booted in safe mode, and I removed the pesky .dll file. I also scanned with spybot, adaware and Trojan Hunter and removed everything they found.
Is there anything else I can remove?

Sorry about the msconfig thing, I didn't notice you were using Win2K.

Close all windows, scan with HJT, and have it fix the following entries:
O2 - BHO: gcdexrfd - {0450EACE-ED6A-B9C6-A288-FEDCE78D21DE} - C:\WINNT\system32\gcdexrfd.dll (file missing)
O4 - HKLM\..\Run: [WindUpdates] C:\Program Files\WindUpdates\WinUpdt.exe
O18 - Filter: text/html - {4F7681E5-6CAF-478D-9CB8-4CA593BEE7FB} - (no file)

Reboot into Safe Mode, go to C:\Program Files, and delete the folder WindUpdates.

Reboot normally, close all windows, scan with HJT, and post a new log.

To help prevent reinfection, get SpywareBlaster:

and keep it updated!
