New/old Trojan?

[nixsec <nixsec () area66 org>]

I usually use linux as operating system but for games i go with 
windows,i used this installation of windows 2000 SP4 around 6 times(Did 
not do Windows update cause didn't really care about the system since it 
was gaming only), and sygate firewall detected this weird application 
trying to connect to remote site atm-bank.ru, tried looking on google 
for Mmnkijia.exe and could not find anything on it, this application 
hides itself in the folder when using windows explorer to view the 
folder C:\WINNT\system32\ the file would not show up, using tcpview from 
sysinternals i found several ports open:

<Non-existant Process>:976      TCP     xfiles:247      xfiles:0        
LISTENING  (searched on google and said this was a service called 
subntbcst_tftp)
<Non-existant Process>:976      TCP     xfiles:18855    xfiles:0        
LISTENING
<Non-existant Process>:976      TCP     xfiles:21134    xfiles:0        
LISTENING
<Non-existant Process>:976      TCP     xfiles:38493    xfiles:0        
LISTENING

(Tcpview.exe would crash when i attempted to kill the process, when i 
reopened it those ports would still be open i think i managed ot kill 
the process one time or crashed it somehow and few minutes later got 
back up and running)

I loaded up windows in safe mode with command prompt and from there the 
file would be visible, i found also a DLL file which the exe uses called 
Mngepfne.dll (maybe loaded to hide processes and files?) , i backed 
these up for further examination  and removed them from the system32 
folder, this seemed to fix the problem for now and all the ports are 
closed, but i got no idea where it came from! Later i checked the page 
atm-bank.ru and the index page says page not found, so my only guess is 
it accesses that web site and the owners of it can check the web server 
log files to find infected IPs i did a whois on that server name and its 
a few months old only created:  2004.06.26. If anyone has info  or would 
like a copy of the binary files to examine them let me know.

Im thinking of maybe installing snort on the windows system and 
reactivate the trojan to see what happens, would like to learn more on 
windows forensics, any tips or other software good to be used to 
gather/examine data ?
