My comment concerns only the paid Ultimate version. Avast was good to me, combining everything I had previously paid for ongoing lesser subscriptions for different devices into one credit for an Ultimate subscription covering 10 devices. It was a deal as my wife and I now have a single plan for two computers, two tablets, and two cell phone which will last for over two years. Also, when the PC version of Avast wouldn't start on my computer recently, Avast tech support did a good job of getting it running again, explaining the likely reason that it broke and remedying the problem. In two years, things may be different, but I'm happy with Avast for now.
