Wow.. what a good product.. try to use Kerio (with a free 
edition - www.kerio.com)

.. or use a real firewall. For prices starting at $50 
(example: D-Link DI-604) you can have a REAL hardware 
filtering, not affected by trojans or viruses. (when a 
trojan/virus attacks you, it often stops your firewall)
