I know the difference, I read them every few months when I reinstall Win or install a new Avast AV on a client PC, I know it’s altruistic of Avast to give us such a quite complete version for free and just a potential buying option and a quick free registration anualy, under no obligation on their part to do so, I appreciate it greatly but it’s mutually beneficial also, and they don’t need to give a new technology for free neither, but the way it’s offered bothers me, but I guess that’s why I don’t like Capitalism and I advocate for better Economic System, is Darwinian worse than in the jungle: oh you fear that? if you give me something-something, I’ll protect you, I picture a asian descendant in Chicago with a black eye paying some goons for protection that some punks did last night… granted we don’t ahve Internet Police and I hope we never do, but I don’t know, I guess there are better ways to make money than to take advantage of the fear of the people, this is at least morally questionable for me
