Re: firewalls and trojans
The soft-ware firewall is the second line of defense but you still need to clean your system[and repair damage done...over-writing some files?]
For hard-ware firewall you might use a router with nat.

Just wanted to reply to this to mention although this is a good technique it is not a firewall.. routers can do packet filtering but a router by nature is not a firewall.... typically a firewall operate at a higher layer of the tcp/ip protocol stack. Firewall can block traffic based upon IP address but in general they typically block based upon tcp/udp port number to allow specific traffic denying all others.. Just for clarity sake I am sure this is what he ment... :)
OK a harder firewall is a computer that looks at traffic that is passed accross two interfaces. It examines the traffic according to rule you build that will allow/deny the traffic from entering the other interface. Typically one interface lives publically the other privately. The firewall examines the traffic passing between the two ports and makes a decision based upon your rules...
