Try to find which programs/services have opened the port and prevent them
from running or install a firewall and tell it not to allow the applications
to open the port/act as servers

For FTP and Telnet simply disable the FTP server service and Telnet server
service. The best option is to install a firewall though.

Lassek,

The best way to close a port is to close the program opening that port. Are you
running a program that opens port 80? Merely accessing the internet (as a
client) doesn't open port 80 (as a server).

Did you do a security scan that shows that port open? Here are a couple that I
have used:
http://grc.com/default.htm ("ShieldsUP!")
http://scan.sygate.com/

What model Belkin router?

A neat way to close miscellaneous ports, with many routers, is to forward a port
to a non-existent computer. If you were to forward port 80 to ip address
192.168.0.254 (assuming your LAN is 192.168.0/24), and you had no computer at
that address, it would be closed (actually stealthed). See if "Virtual Server"
is a port forwarding ability.

If you want to find out about unknown programs opening port 80, get Port
Explorer (free) from
<http://www.diamondcs.com.au/portexplorer/index.php?page=home> to show you what
network connections your computer is actually opening, and what processes are
opening them. And Process Explorer (free) from
<http://www.sysinternals.com/ntw2k/freeware/procexp.shtml>. Provides way more
information than Task Manager.
