Not quite true..
You need to find open ports then you must run a trojan on their computer. Usually sent via malicious email or some sort.
I'm behind a NAT so I don't bother with a firewall and Windows XP seems to have it's own anyway (don't know if it's any good!).
Firewall isn't totally necessary but antivirus I would recommend. LK I'd be interested to see if you found any viruses if you were to do a scan..
