System integrity
It’s important to protect your system against electrical problems and physical
hazards such as heat, moisture, and dust. It’s also important to protect it
against less obvious hazards such as viruses and hardware overloads.
Protecting your computer from viruses
A virus is a program that attaches itself to a program or data file on a computer,
then spreads from one computer to another. Viruses can damage data, cause
computers to malfunction, and can display annoying or offensive messages.
Some viruses can go unnoticed for long periods of time because they are
activated by a certain date or time. Protect your computer from viruses by:
■
Using the Norton
®
AntiVirus to check files and programs that are on
diskettes, attached to e-mail messages, or downloaded from the Internet.
After you run Norton AntiVirus you can back up your files to diskettes,
a separate hard drive, or a high-capacity storage drive.
■
Updating Norton AntiVirus periodically to keep up with new viruses.
■
Obtaining all software from reputable sources and checking the software
for viruses before installing it.
■
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.
To remove a virus:
1
Find and remove the virus immediately using Norton AntiVirus.
2
Turn off your computer and leave it off for at least 30 seconds.
3
Turn on the computer and rescan for the virus.
