I don't know if the project description you saw was for Samba4 or
Samba3, but certainly I would like to see someone write a Samba4 NTVFS
module for interfacing with anti-virus products. The existing Samba
anti-virus interfaces leave a lot to be desired I think.

It's a non-trivial project though, as you have to take care that a
virus can't bypass you in some way. For example, a virus might bypass
a 'check on close' implementation by leaving the file open, but with a
share mode that doesn't prevent it being opened by another user.

So you have to think pretty carefully about exactly what you check,
and when.

Cheers, Tridge
