A firewall has to do with network traffic. All this talk about "bypassing firewall x or y using this trick or that one" is sheer nonsense. It is not the job of a firewall to track all the relations of executables and/or API calls in the system. I never heard anybody complaining that iptables allows a script execute Conqueror to communicate with a server.
Use an antivirus program or an IDS for this job. Andrei Aditya Deshmukh wrote:

This is the reason most firewalls like show you a popup saying the [app-name] trying to connect to [server-name] at [port-number]________________________________________________________________________ Delivered using the Free Personal Edition of Mailtraq (www.mailtraq.com) _______________________________________________ Full-Disclosure - We believe in it.
