First up, I cannot see where hijackthis is running from. This is important, so please let me know. It should show in the log.
Second. Unless you get service pack 4 for W2K and install IE6 with service pack 1, you stand an excellent chance of being instantly reinfected.

Please go here & install ALL critical updates required for your system, including service pack 4 for W2K and SP1 for IE6.
Most malware is designed to attack unpatched systems - exploiting the available 'holes' - and can bypass third-party protection on an unpatched system. The most that can be done with an unpatched system is put a temporary bandage on it. your system can potentially be reinfected within minutes of cleaning it.

Please post another log when done.
