Okay, I don't get it. By now, every single free AV, BAR NONE, has heuristics. Except for one: Avast 4 Personal Edition, which only has heuristics for mail scanning. What's with this? Is Alwil Software going to bring their AV up to date, or is it on the fast track to becoming a dead AV? Or does the professional version have heuristics? If so, they ought to mention it in the info-thingy in the free version, since not mentioning a key feature of a product is bad advertising.
