It's the age old problem of computers for idiots. The basic user (the granny emailing her grandkid) is scared witless that the terrorists can turn her computer into a bomb using an email virus (i read one of those help desk support story sites and that was actually one of them) so they get this lad on to calm their fears. It seems like it was computers dumbed down for people that still leave cheese beside the mouse and tipex out mistakes on the screen.
