I don't want to speak too soon but from what I have seen so far ZAES v9 is one of the best complete security suites I have ever used. It has a relatively low resource usage, runs smoothly, it has state of the art security features, its highly compatible, it seems to work well with other ASW software like SAS and MBAM, and has a low number of annoying alerts to deal with. The ForceField browser security support with the virtualization component for BOTH the IE and Firefox browsers is a HUGE plus and was a major factor in my decision to go with ZAES v9. I have just ZAES v9 for security software running on my PIII 1Ghz notebook with 512MB RAM, Windows XP Home SP3, and it runs efficiently enough to make that old notebook very usable for common web browsing, multimedia viewing, etc.. It runs better than when I was using the combination of NAV 2003 along with ZA Free for security on it seven years ago.
