Troubleshooting
8 - 4 Viruses

Viruses
• Install an
Anti-Virus
program and keep the
definitions
file
(the file which tells your program which viruses
to look for) up to date. New computer viruses are discovered daily, and some of them may seriously harm
your computer and cause you to lose data.
Anti-Virus
programs are commercially available and the
defini-
tions
file updates
are usually downloadable directly from the internet.
• Be careful when opening e-mail from sources you don’t know.
Viruses
are often triggered from within
e-
mail attachments
so take care when opening any attached file. You can configure most
Anti-Virus
pro-
grams to check all
e-mail attachments
.
Note
: You should also beware of files from people you know as the
virus may have infected an
address book
and been automatically forwarded without the person’s knowl-
edge.
• Keep a “
Bootable CD-ROM/DVD-ROM/USB storage device
” (this CD/DVD/USB device provides basic
information which allows you to startup your computer) handy. You may refer to your OS’s documentation
for instructions on how to make one, and many
Anti-Virus
programs will also provide such a disk (or at
least instructions on how to make one).
