Need help removing a SMTP relay.

Hi all,
I have a terrible spam bot I can't seem to find.  In TCP View, I've found PID 732 (services.exe) is rife with smtp connections but I ony see EventLog and PlugandPlay when I look at it via tasklist /svc.  Antimalware Bytes comes up with nothing as does Prevx, Vipre  or Trend.  Also, system restore is missing from Computer properties.  I'm going to try running Stinger, but I haven't had any luck with that in years. I can always block port 25 in windows firewall, but I'd rather a real solution.  Any help would be most appreciated.

BTW - It's an XP SP3 workstation on a SBS 2003 domain. (removed from right now ;-)

Open a command prompt and type "netstat -b -a" to display all open ports and the executable associated with them.

Run TdssKiller and Hitmanpro.

If still having issue run Combofix and post log here

>If they still dont run, redownload them but rename them prior to saving them

Every smtp connection to a foreign address is PID 732 - services.exe.

Most of the connections are Established.  Some are closed and some are Wait.  Since I can't even identify the infection, I beginning to consider a nuke and pave.  I need to have the ws back in place in the morning.  User was off today so I had some play time.

Try those scanners if you have time. Shouldn't take more than half hour to run all :)

I'm going to flatten it.  Nothing has worked so far.  I am able to find a few entries in HKLM that are hidden from the Windows API, but I can't get to them or find the associated files.  Time to push the button.  Thanks to all of you.
