That reminds me, we did get a Microsoft Word virus passed on to us from one of our pc clients many years ago and the problem still exists. I believe it was called the Melissa virus.
It's a weird one. If you save a Word file when the minutes of the hour match the day of the month, lets say at 12:05 on December 5, text is inserted at the top of the page that says:
"Twenty-two points, plus triple-word-score, plus fifty points for using all my letters. Game's over. I'm outta here".
Every now and then it pops up and can be very annoying.
