Chapter 13: Maintaining Your Computer

www.gateway.com

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.
