I just installed Norton Firewall 2006 and NAV 2006 under Win XP Pro, but the Live Update is haveing a problem downloading updates for the intrusion detection signatures. All other downloads under Live Update work fine, but Intrustion Detection Signatures is always marked with a red 'X,' meaning that it's not working properly. Needless to say, it never indicates the availability of any new downloads, nor tries to install them.
Does anybody know what's wrong and how to fix it?
