Virus definitions? What are those?!
It never surprises me to see a middle aged housewife from Wisconsin who uses her computer to play pogo.com games and look up recipes not really know why she shouldn't use the oh-so-useful Weather Bug program or to understand that a firewall is never going to protect her computer from a virus.
It always suprises me when I see supposedly computer literate 20 somethings use Google (the name of a company that assumed everyone in the world was too stupid to know how the word "googol" was pronounced) as a verb.
But it really *shouldn't* surprise me. It just does.
