Yeah! Unfortunately that´s true. But as i never have gathered 
information about that i thought someone could have Statistics that 
could show that a particular trojan/worm is more active in the internet 
and it uses a specific port. But all points out to any port could be 
used making it dificult to filter connections at Service Providers.
