I'm making my annual check into avast updates. At this point see no reason to change. 2014.9.0.2021 (June 2014) is still working on this XP SP3 box. The only reason I might update is if the GUI has improved. I find it very difficult to negotiate and find anything. Too many complicated "features", 95%+ of which I don't want anyway. For example I had to spend almost an hour to figure out where the exclusions and virus chest are located then make suitable entries. Fortunately I don't have to do that very often, once a year is plenty.
