    The work you do on your computer is valuable to you and to your family. There are many dangers that can result in data loss. The most important thing you can do to protect the information you cannot afford to loose is regularly back it up. Computer viruses are a significant hazard. If you receive digital information by diskette, CD, over the Internet, or by any other method, you are at risk.
