I have found neither Zone Alarm nor Norton software to be of any use whatsoever for protecting a Windows machine that is connected to any network, anywhere. Either vigilant management and constant user re-education, combined with almost any AV software besides Norton et al, or a *nixlike firewall with "deny ip from any to winbox" are the only solutions that seem to work with any degree of guaranteeable success. I would certainly agree with the poster who suggested you contact ISC directly --- possibly something is amiss there, but there is also no guarantee that the IP address being fed to ZoneAlarm is spoofed; this is not at all beyond the means of almost any spammer working today, although the issue of whether they'd go to the trouble may merit some debate. Notwithstanding that, this post is rather OT for this list. Kevin Kinsey
