tcptapi process slowing down machine

I have a windows 2000 professional machine that is very slow running any apps.  I went to Task Manager and looked at the processes.  I noticed one called tcptapi that was using up to 98% of the processor at times and 40% at the lowest.  I kill that process, but within a couple seconds it starts up again.  I searched the registry for tcptapi and found it in HKLM/Software/Microsoft/Windows/CurentVersion/Run.  It was call *tcptapi with a value of C:\winnt\cursors\tcptapi.exe.  I go to that directory and there is no tcptapi.exe there (Hidden files are being shown).  I do however find a tmp file called ipatpct.tmp.  This cannot be deleted while the tcptapi process is running.  I then log out and access the computer from another computer on the network to delete that tmp file.  So, I now have both the registry key and tmp file deleted, but once I log back in the registry key is back, the process starts back up, and the tmp file has returned.  At least this time I can stop the process without it immediately starting again.  I can remove the tmp file again, along with stopping the process, and removing the registry key, but as soon as I log off and back on, it is back.  Any suggestions?

Have you tried running AdAware and Spybot on the system to help clean it of any malware crap?

Adaware http://www.lavasoftusa.com/software/adaware/

And

Spybot http://www.safer-networking.org/en/spybotsd/index.html

Run them both in safe mode and normal mode.

Also make sure you update both programs before running them.

Thank you!  After updating Ad-Aware, it found the culprit.  It was some Spyware called Virtomundo.  I believe the file that kept running the process was called tcpole.exe.  It found a couple others related to this spyware also.  It did only find it after the program was updated though.
