Nessus check for some vulnerabilities in the ircd daemon, but I don't
know if that suits you in any way.

It's quite difficult to secure this kind of network at the server,
I better would be looking at the Win32 clients.

The best you can do it's having an antivirus in each Win32 machine, in
daemon mode (always loaded), so it can detect any of the virii or worms
that users can download via IRC/DCC, email, or file sharing. It's the
easiest way to do it, but you can also try to use a corporate antivirus
in the server in daemon mode scanning for all the downloads.

mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
