trophie and virus defs

Hi all,

Does anyone know how to get trophie to 'see' virus defs?  Whenever I run
the program I get:

[root@frank2k3 trophie-1.12]# ./trophie 
VSReadVirusPattern() failed (return code: [-4])

How do I tell it where to read the latest virus def files?

Also, is there a trophie virus def update script similar to
sophos-ide-update for sophie?

thanks
Chris
