Vote for the tech you think its the best if u need more infos read the following http://www.viruslist.com/en/analysis?pubid=189801874
arent Heuristic Analysis and Behavior Blockers simply a form of Proactive Protection? in that case ill just vote for Proactive Protection. heuristics are important because they are effective and at the same time, dont have as much "False positives" as HIPS and such. behavior blockers are also good because u can prevent damage from viruses, however it requires user interaction.
I agree with WSFUser regarding behavioural and heuristic analysis. Both are forms of proactive defense rather than reactive.
