Any time someone says there are viruses on the Mac when there are none
I WILL go of like a bomb, at least until the first virus actually
shows up. Many people here coming from the really scary world of
Windows do so because they heard it was safer. Well it is. People also
come over to Mac because it is easier to do everything that you really
need to do like your own work. Mac users do not need to be computer
guru or have one on call to use the thing every day. I get just as
annoyed when people give advice to someone like my mother to use the
terminal to enter cryptic codes to do things that there is an
application for. 99% of Mac users use a Mac for the GUI not for the
terminal.
