Computer Viruses
Like viruses that infect humans, a computer virus contains instructions for its own
proliferation and is potentially very harmful. Though some computer viruses are just playful,
most are dangerous for your computer and data. For example, some viruses destroy the file
allocation tables, so that your computer cannot locate files or software . Some viruses are
programmed to become active on a certain date (e.g. April 1 or Friday 13) or when you
execute a certain command.
Programs are available that scan diskettes and hard drives for viruses. Some of these
programs will also remove the virus . These programs can be set to test the computer for
viruses every time you power up. To protect your computer from viruses, you should also
scan every outside disk before using it. Write-protect your software diskettes so that they
cannot be infected. Avoid programs and diskettes from unknown sources. Only buy software
in sealed packages.
Networks, the
Internet and bulletin board services represent special risks. Use only well
known electronic bulletin boards. If you plan to download software from the bulletin board,
ask the service what steps it is taking to guard against viruses.
If your computer is behaving erratically, it may be infected by a
virus . Check out the
problem before proceeding further.
There are more than 100,000 known viruses out there. Although there are thousands of
viruses identified each year, there are still some that only exist in the imaginations ( virus
hoax) of the public and the press.
