CISCO ACLs.. Are there lists already out there to protect me from trojans and known bad sites?

["Pigeon" <fredit () charter net>]

I just got my first cisco router in (well for home use :) ).. and I want to 
lock my network down.. Are there any default ACL lists that will block:
A) known bad IPs
B) trojan ports
C) protection against spoofing (aka denying  private IP source port incoming 
in the WAN port)

I know I will have to modify whatever I have.. but a general list would be 
great!

thanks!
