An IRC-worm is a type of worm that uses Internet Relay Chat (IRC) networks to spread copies of itself to new host machines. An IRC-worm typically spreads by first dropping a script to the directory of the IRC client on the infected machine. Subsequently, whenever the infected client connects to an IRC server and joins any channel, the script automatically causes the IRC client to send a copy of the worm's executable file to every other user who joins the same channel.
