1. You should create a specific folder for HJT, c:\HJT would do rather than have it dumped on the desktop. If you make any fixes you really want everything in its own folder.
2. This is possibly one of the smallest HJT logs I have seen in some time. I don't know if this is because you are running win2k or some other reason. I would suggest once you have created a folder for HJT that once installed you rename the hijackthis executable to Tl12000HJT.exe incase there is malware that detects and avoids HJT.
You didn't answer the question about the malware name as that could give us an idea if you do indeed have a file infecter at work.
If you haven't already got this software (freeware), download, install, update and run it, preferably in safe mode and report the findings (it should product a log file). I'm not sure if it runs on win2k but I would think it might.
