I'd recommend a hardware based firewall: they're fast, secure, and cheap, around US$100. (Remember to change to default admin password!) Often they have features such as a wireless access point, VPN access (secure remote access), a network switch and/or a print server. For households with children, it can limit internal users' Internet access based on URLs and/or time periods Since it's not Windows based, it's less likely to compromised. Generally they're pretty easy to setup. By the way, this doesn't eliminate the need for up-to-date virus protection on each PC.
