Why do you need a software Firewall?

Again we see this subject just won't seem to die. Everyone wants to bring a new spin and yet another thread into the mix. My reply to the latest thread can be found below.

As was mentioned above = layers. What if your antivirus or antitrojan solution misses a trojan or worm? When this malware decides it's time to phone home. A software firewall will clue you in – if your an alert user. No software or hardware solution will keep a dumb user safe from themselves. But properly configured protections can help to make some things a bit more idiot proof. If your router gets compromised in some way. A software firewall is a good backup layer. If your running a wireless network and it becomes compromised. Again a software firewall would be a good failsafe. This topic has been beat into the ground in the past and the past several weeks.
