Protecting your computer from
viruses
A virus is a program that attaches itself to a file on a computer, then spreads
from one computer to another. Viruses can damage data or cause your computer
to malfunction. Some viruses go undetected for a period of time because they
are activated on a certain date.
Protect your computer from a virus by:
■
Using the Norton
®
AntiVirus program to check files and programs that are
on diskettes, attached to e-mail messages, or downloaded from the
Internet.
■
Checking all programs for viruses before installing them.
■
Disabling macros on suspicious Microsoft Word and Excel files. These
programs will warn you if a document that you are opening contains a
macro that might have a virus.
■
Periodically updating the Norton AntiVirus program to protect against the
latest viruses.
