I use Zonealarm on my home PC.  I love it!  It has so many features and you can find out exactly what appz are using the net and who is pinging, portscanning, or trying to hack you.  I have used it to catch hacker a couple of times for some friends of mine.  The best feature that i like in it is that you can totally shut off all incoming traffic..so you are still on the net...but people cannot even ping you.
