Trojan ntos.exe on Win2000 urgently need instructions for removal

[elfwood]

The header says it all.
F-secure noted the malware, so I plugged it off the network. It could not disinfect and I could not remove manually any of the elements related.
All isntructions I found so far are for XP and up but this system is a 2000Pro.
What need I do to get it clean and safe to use.
Also, Need urgently to know
-Is it safe to have on on my LAN, or can it in any way infect other PCs.
-Is it safe to send Word or EPS files created on this system to my client? To send them I need to attach them to a mail msg sent from another system, which I checked and noted clean.

Million thanks in advance

hi elfwood

still need help? need to post a hjt log as a starting reference point.
the optimal tools dont work on w2k, but we can try a commercial app.

this is a trojan capable of uploading your sensitive/personal info.

you should pull the plug to this machine at your modem or router
