Frustrated Son asks: "I assume that many Slashdot readers must serve as the IT staff for their parents. My folks get my old machines and just enough software to be productive. I try to protect my parents from the forces of evil by installing automatic OS updates, virus checkers, spyware blockers, pop-up blockers... But still I find that my parents end up with unwanted applications and dangerous software. What software or strategies do you use to protect your parents' PCs? Is it possible for inexperienced users to surf the net in safety?"
