Chapter 5: Maintaining Your Computer
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:
■ Registering your copy of Norton
®
Internet Security and subscribing to the virus
definition update service. You received a free limited time subscription to the Norton
Internet Security service when you purchased your computer.
■ Using the Norton Internet Security program to check files and programs that are
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 Internet Security program to protect against the
latest viruses.
■ Making sure the Windows Security Center is configured to provide you with the
highest level of protection.
