I am often asked "which is the best anti-virus software?"  For most people, the internet is becoming more central to everyday living.  Another phrase i often hear is "there's no real rush for it," when I’m picking up a computer for repair.  However, if it's not back within a day the phone starts ringing: with comments like "i just need to........” you get the idea.  Anyway, the keyword is "need".  We all need our computers now.  They are no longer a geeky work tool for the minority; they are a central communications device in most homes.
