Someone said earlier that most Aunt Mabel's rely on sons, daughters or nephews. Or, from what I've seen, next door neighbor. The thing is, not every son, daughter, etc is readily available and not all of them are going to download the client--not necessarily because they are hugely honest, but because they know if Aunt Mabel wanders into a virus later, they are on the hook to "fix my computer."
And none of the Aunt Mabels are going to go through that whole sequence on her own. I have called some of the ladies in my cozy group to walk them through things on the phone and once past the second instruction and we aren't done, panic sets in.
WHAT?? MY BOOK IS ON A TORRENT SITE????

Who knew!!
