1. Yep, free updates for 1 year, but you gotta register. Right now there's an 3.13 meg update waiting for you(ver2.6.362)When you register, Zone Alarm sends you a new License Key so you can get the free updates(took them 4 days to e-mail it) 2. Yes, you have to uninstall the free copy first. Go to http://www.zonelabs.com/services/support_install.htm for the instructions. It's more than just turning off the icon in the system tray, you have to turn off the TrueVector Service, too. 3. Haven't heard anything yet about when ZA3.0 is due.
I've still got a lot to discover what the Pro version does. One thing it did already was to quarantine an attachment which was probably harmless. Was curious because Norton AV scan said it was clean. Turned out it was an electronic Christmas card that had an ".exe" extension. All this kind of stuff can be fine tuned.
