Win2000 prevents the deletion of any file it considers a
system file, and obviously part of the trojan was to not only plant various files but to have Win2000 "see" them as system files. In that case, assuming you didn't setup a dual-boot system, you will need to boot your computer from a boot floppy to a DOS command prompt. Hopefully you have a boot floppy left over from Win98 or WinMe, if not maybe a friend does. If your harddrive is formatted with FAT32 you will need a version of DOS that supports FAT32 (like OSR2, Win98, WinMe) so that the utilities will function properly.
The trick once you're booted from the floppy will be to work your way around to the various folders (or directories as they used to be called) so that you can delete the files that you've determined are causing the problem. You may need the DOS attrib.exe file to first remove the hidden or the system "bit" so that the delete command will work.
If you do not have a dual-boot setup (i.e., Win2000 and W98), and are not familiar with DOS, you will need someone who is comfortable there, as this is not the time to attempt to learn DOS. Assuming you are able to delete the files you will later need to go into the Win2000 registry and remove all references to those files.
[later edit:] Just read Macal's post. If these processes are running in the background hit Ctrl-Alt-Del, click Task Manager, click Processes. Then fish thru the processes and click End Process. Of course, make sure you are deleting a trojan process.
