Do....you not know anyone who is not particularly tech-savy and owns a PC? Have you ever looked at one? Have you ever seen the gigantic amount of programs they have downloaded, that were not actually the program they were looking for, but was instead a malicious software? I'm hoping your "nobody" refers to the general populous of this form, and not the general populous of the world, as we, people like us on this forum, are a minority. Anyone who has ever done PC repair, or helped out their family/friends, knows this.
