Avoiding data loss or damage
In recent years, many computer users have experienced problems with viruses -
- malicious programs that damage files or erase disks. A virus could be
introduced into your Macintosh system from a disk you or someone else puts in
its drive, from a network device such as a file server, or from an electronic
bulletin board service.
You can use any of several virus detection and elimination programs to check
your Macintosh disks regularly for viruses. Such programs are available from
user groups, computer bulletin boards, and dealers.
Even if you do not notice problems with your computer's operation or the
information on your disks, you should check for viruses frequently if you
exchange disks or information with other users.
A good virus prevention strategy includes these practices:
- Work with backup copies of programs so that the originals will not be
corrupted by a virus.
- Make backup copies of your work frequently so that you can restore any data
that might become damaged.
- Check your primary disks regularly with a virus detection program and
correct any problems it finds.
- Whenever you get a disk from anyone -- even a commercial source -- check it
for viruses before using it or copying anything from it to your system.
- If your Macintosh is on a network or if you use a modem to connect with
information services or bulletin boards, check for viruses as often as it is
practical -- ideally after each time you copy any information from an outside
source.
- If you are part of a work group that includes a number of Macintosh users,
set up a "virus detection station" that everyone can use to check disks (and
to copy the latest version of virus detection software if your group has a
site license for it).
- If you give information to other Macintosh users on disk or send
information electronically, make certain that there are no viruses on your
system before distributing the information.
