I once considered setting up a scheme of proxy servers to deter anyone trying to worm their way into my computers.
But I believe AVG software and a good Firewall provide enough protection.
But I still worry about keyloggers and such breaking in. I started checking out keylogger detector software and in a trial run the first two products said I had one. But I thought they were probably just trying to scare me into buying their software.
If anyone knows of a 'clean' keylogger detector, please pass it on.

AVG is excellent software; free, too! But you should update the virus definitions database at least once a week.
IMHO, a firewall that protects against just inbound threats, such as that built into Win XP SP2, is worthless as it does not protect against unwanted outbound traffic such as keyloggers calling home.
FWIW, I use the free(!) Kerio firewall. Excellent!
