Buddy:

Have you tried BHOdemon to see if it is a Browser Helper Object
?http://www.definitivesolutions.com/bhodemon.htm ?

I also suggest going to Sysinternals --
http://www.sysinternals.com/ntw2k/utilities.shtml and obtaining both TCPVIEW and Process
Explorer to find what are the dependencies are what DLLs are associated with this Trojan.

I also suggest repairing AUTOEXEC.NT and CONFIG.NT, then rebooting into Safe Mode and
scanning with F-Prot...

AUTOEXEC.NT and CONFIG.NT Fix Method 1:
copy; c:\windows\repair\autoexec.nt
to
c:\windows\system32

and

copy; c:\windows\repair\config.nt
to
c:\windows\system32


AUTOEXEC.NT and CONFIG.NT FIX Method 2:
Go to; Start --> Run
enter; cmd.exe

{ assuming the WinXP CDROM disk is in drive "D:" }
In the Command Prompt enter...
expand D:\i386\autoexec.nt_ %windir%\system32\autoexec.nt
expand D:\i386\config.nt_ %windir%\system32\config.nt


The last time you posted about this you indicated F-Prot found; W32/backdoor.AOP
now you are saying it's; W32/backdoor.SO

When I do a McAfee search on upnpclient.exe and acrobat.dll, I get the following...

BackDoor-CLS -- http://vil.nai.com/vil/content/v_130352.htm

Please send me an email so I can provide you with more information. It is for a licensed
product so I can't post it in public.
