I've been using ZA free for a couple of years and I'm ready to upgrade to ZA pro. Questions -1- Does ZA pro install over ZA free or will I need to uninstall ZA free before installing ZA pro?2- Will I have to go through the series of pop-up promps asking which programs are allowed again?3- Will ZA pro get along with my AVG free? Thanks - Keith
