When I clicked F3 then Default would highlight with zaMailSafe next to it and I happened to notice a little folder open on the left. I deleted each default (on the right) but the little folder remained on the left. I left those (because this was making me nervous). But it seems to me that the free ZoneAlarm carries all the extension. I know people have questioned that.

I can answer that question Nancee - Mailsafe in some versions of ZoneAlarm free version is only supposed to protect you against against two or three suspect attachments but in fact give the full protection of Zone Alarm Pro (37 file types). That was what you saw in your registry. Just checked the latest release, unless my browser is acting up, it seems that Zone Alarm free does not now offer MailSafe protection.
