I have a Security question to do with multiple PC's accessing the Broadband Internet via modem

[Guest]

I have 4 PC's that all access the Internet. All 4 PC's which run Windows XP Pro connect to each other via an 8 port mini hub. The Primary PC connects to the Internet via a Broadband Modem. This Primary PC is running a Firewall and Virus Protection (Mcafee) but the other 3 PC's only have Virus Protection (AVG v7 Pro). Do I need to install a Firewall on each PC?

Yes, or switch your broadband router to one with a built-in packet filtering
firewall - they're pretty cheap. Running software firewalls on each computer
will be a bit more cumbersome, esp. if you want to use file/print sharing
between them....

I agree. Windows XP needs a firewall. Even n a dialup. If you're on
broadband, shell out the extra $40 and get a router with a hardware
firewall.
