Hi all, I have a problem with Norton Personal Firewall. Under "Options", I choose "Norton Internet Security" and then the LiveUpdate tab. I then tick the "Monitor for updates to Intrusion Detection" checkbox (which it lets me do) and OK it. However, when I look at the options again, the checkbox is unticked. Anybody out there got Norton Personal Firewall 2004? Maybe you could try it - and let me know if it works for you? By the way, the other checkboxes on that same tab allow me to tick them - and they stay ticked! Any help would be appreciated.
