Hi, folks: I have been using this now-called AVG AS since pre AVG era, but never have fully understood how effective its guard is. From what I can gather from here and there, it seems just scan memory and applicatin execution, not a so-called real time scanner we all are accustomed to. And mind you, it is this guard feature separating paid and free version(beside the auto update). That $$$ might not be a big issue, but what does happen when it becomes a thorn in someone's throat. I just wish they can give us a clear mandate of its feature.
