Ok I need some advice. First things first this NOT a A vs B so keep the comparing comments out of it please no need for it. if you cant I will asked for it to be closed. What I do need is what you would use for a Enterpise based system. I have a few hundred clients I need to switch out. What I'm looking for is your Recommendation on what to use on that end. I don't need a explanation why as I can test them out my self but I need a few choice's to try. Things that I do need Easy to deploy (not spend 400+ hours installing on every computer) Decent Resource usage. (not something that is going to drop them to there knees) If you need anymore info from me ether PM me or ask it here. The servers are running Windows 2k3 and 2008. There is a mix of XP and 2000 Client computers. all the computers have to use the same software. I cant be mixing AV's Thanks again.
