Question : SBS 2003 Persistant Virus

Our SBS2003 server keeps getting the same virus, so it seems.
We have TrendMicro Worry Free Business Security Advanced with realtime scan but we still manage to get the same malicious virus/services reappearing.

The services are:
es4drv with display name of: 360
wsfseda60 with display name of: wyerdss60 mseir

The main files that I see often are:
c.exe
UBCACBA.EXE
...and associated DLLs
I was wondering if any of you have seen this before or have any ideas of how I can keep this from reoccuring.

P.S The virus definitions are up to date, the SBS 2003 has all latest patches, all computers attached to the network have the Trend Micro client installed and up to date.
