I recently downloaded and added Avast AV free version to my wife's laptop and she just started getting a pop up from them which indicates that her free trial is about to end. Checking their site at the bottom it does indeed say the free AV is a 30 trial. But I have had it (the free version) on my desktop for quite a while and never got a notice telling me a free trial was about to end. Did something change recently? I don't remember where I downloaded mine from, is there another site to DL a forever free version?
