Best WEB Server Virus\Firewall Software?

IMNSHO, there's no such thing as "best".

Certainly the "best" firewall for any microcomputer O/S is a separate appliance. However, if you absolutely "must" run the F/W on the W2K, ZoneAlarm or Black ICE Defender seem to get high marks.

As for AV, it depends on what else the box is running, and the intent of the AV. For instance, TendMicro has a respected AV that you want to run on an email server. If all you want is to protect the PC itself, then any of the big brand names (Trend, Norton,NAI/McAfee/etc.) will do just fine. If this PC is also going to dish out updates to clients across your internal network, then look closely at the Enterprise editions, and make sure they are appropriate for your environment. Pay special attention tofeatures like management consoles, automatic updates, push/pull, and so on.
