RE: Port 80 open without WebServer

["Hamish Stanaway" <koremeltdown () hotmail com>]

Hi there,

It is my understanding that many web browsers operate on a local port 80. 
This means that not only do they connect to the web server on port 80, but 
open port 80 on your own machine. This might explain why your port 80 is 
open.
Do the audit again and makesure you have no web browsers open at any stage 
of the audit, then see what happens - you might just find that port 80 is 
closed.

Kindest of regards,
