I know that some of folks don't think that doing virus detection with

Wow - freaky!
:-)
Have you got any stats on how such a preprocessor affects Snort?
e.g. how much more CPU/memory load, FP rates, etc.
No, although with no hard data i can say the load seems to be ok.
As far as FP rates go, I mean as it's "just" an AV preprocessor (now
there's an understatement!), I assume it isn't also a SMB preprocessor - so
it isn't translating raw network data back into files before letting ClamAV
loose on it
You are correct.
- so the chances for FP must be higher due to that.
Well, maybe you are right, but i'm running it for a few weeks now, and haven't
seen any fp. But this is one thing we need to find out by heavy testing :-).
Regards,
Victor
