I do everything that you do. Then I make a new folder and place it on the
idiot's desktop labelled ONCE A WEEK
I then install CCleaner, Malwarebytes, SuperAntispyware, AdAware, Spybot and
Advanced System Care and put all their shortcut icons into the folder. I do
this for myself too, plus a couple of others, but that lot is enough for
most people to cope with. I get very few callbacks except for completely
different problems. It isn't idiot proof, but coupled with Avira for AV it
is simple end effective without hitting anyone's pocket. I leave it to the
idiot's decision whether to upgrade any of those programs to the paid
version!
