Managing Your System

System integrity

Protecting against viruses

A virus is a program written with malicious intent for the purpose of creating

havoc in a computer system.

Viruses spread through executable files, document macros, or boot sectors.

Diskettes used in a contaminated computer can get a virus and transfer the

virus when used in another computer. A virus can also spread through files

downloaded from bulletin boards or the Internet.

Some viruses may only cause your system to beep or display messages or

images on the screen. Other viruses are highly destructive, and corrupt or erase

the contents of your files or diskettes. To be safe, never assume any virus is

harmless. Always protect your system against viruses.

To protect your system against viruses:

■

Use Norton’s

AntiVirus to scan your computer regularly. Make sure to

update Norton’s

AntiVirus periodically to keep up with new viruses.

■

Make backup copies of all files and write-protect the diskettes. A virus

cannot infect a write-protected diskette.

■ Obtain all software from reputable sources and always scan new software

for any viruses before installing it.

■

Be cautious about files you receive in e-mail or download from a network

or the Internet. If you download a file, use your virus checking software

to scan the directory on your computer that contains the downloaded

file before you open the file.

■

If you have doubts about the source of a Microsoft

Word or Excel file,

disable the file macros before opening the file. Word and Excel are set

by default to warn you if a document you are about to open contains a

macro that might have a virus.

Important To protect your system against electrical problems and

physical hazards such as heat, moisture, and dust. Also,

to protect it against less obvious hazards such as viruses

and hardware overloads.
