I don't see much support needed for win98. The only thing MS really patches is IE holes. Win95 only supports up to IE 5.5, when was the last patch released for that? As for virus protection, you need antivirus software. It's always been like that. The only major virus outbreak outside IE/Outlook is from the RPC vulnerability, and that was on win2k/xp only anyway...
I don't see the similarities between Windows XP and the new coke myself...
