IRC Defender is a Perl program for protecting your IRC network against virus drones, general troublemakers, ban evasion, and attacks. It is fully modular, able to unload and load modules on the fly, and comes with several modules to ban anatoly/fyle virus drones, block unauthorised cgi:irc sites, conduct ctcp version surveys, maintain ctcp version blacklists, and (most importantly) set regexp-based akills.
