Computer viruses plague our frail hard drives like, well viruses.  The scary thought is that these viruses that can wreak so much havoc and mayhem are usual the creation of geeks like you.  More impressively, these viruses can provide jumps in programing and development.  Even now the lines between virus and spyware and helpful program are becoming tangled as the software is starting to mimic each others practices.  Not to say viruses are good, but progress is progress.  The likely first computer virus appearing in the early 1970s called Creeper.  It infected computers through modems posting text "I’M THE CREEPER : CATCH ME IF YOU CAN."  Viruses evolved throughout the years, mutating into harder-to-find-and-kill programs.  The term computer virus itself began in 1984, coined in a paper by Frederick Cohen as suggested by his teacher.
