You create An Access List

say for example

access-list 101

deny ip any any eq 6667
deny ip any any eq 1214
deny ip any any eq 135
deny ip any any eq 137
deny ip any any eq 138
deny ip any any eq 139

save that lot

blocks IRC Kazaa Messenger Spam and the Netbios Ports for starters. Add more in the same fomat

google for kazaa gnutella bearshare limewire etc
