Hi, Just to say that Kerio is not very usable - I have installed it here, and it is fine, but the UI does not really speak well. There are sundry buttons on the top and down the side that cause issues, and the data in the screen does not speak using the tab key. I would just stick with the standard AVG7 and XP service pack 2 firewall, if you are using older then get Sygate. Andrew.
