>Frank, zonealarm has parental control along with virus and spam blocking. So far it's blocked inappropriate stuff for my daughters. Apparently it doesn't have all the features of some other parental control options - e.g. time limits- but IMHO it's useful to have a single package providing firewall, virus and parental control rather than multiple installs slowing down your machine.

Thanks John, I used to use ZoneAlarm as a firewall way back, but stopped when I got my broadband which came with a firewall. I'll check it out too.
