Chapter 4: Keeping the computer safe

Protecting the computer from viruses

When you use the computer for e-mail or Internet access, you expose it to computer viruses that can disable the operating system, programs, or utilities or cause them to function abnormally.

Antivirus software can detect most viruses, destroy them, and in most cases, repair damage they have caused. To provide ongoing protection against newly discovered viruses, antivirus software must be kept up to date.

Norton Internet Security is preinstalled on the computer:

■Your version of Norton Internet Security includes 60 days of free updates. It is strongly recommended that you protect the computer against new viruses beyond 60 days by purchasing extended update service.

■To access Norton Internet Security, or to get more information about it, click Start, click All Programs, and then click Norton Internet Security.

Protecting your system files

The operating system and the backup and recovery software provide several ways to back up the system and to recover optimal system functionality. For information, refer to Chapter 6, “Backup and recovery.”

Protecting your privacy

When you use the computer for e-mail, network, or Internet access, it is possible for unauthorized persons to obtain information about you or the computer.

To optimize the privacy protection features of the computer, follow these guidelines:

■Keep the operating system and software updated. Many software updates contain security enhancements.

■Use a firewall. Firewall software monitors incoming traffic on the computer to block messages that do not meet specific security criteria. Some firewalls also monitor outgoing traffic.

Protecting the computer from power surges

To protect the computer from the power surges that may be caused by an uncertain power supply or an electrical storm, observe these practices:

■Plug the computer power cord into an optional, high-quality surge protector. Surge protectors are available from most computer or electronics retailers.

■During an electrical storm, either run the computer on battery power or shut down the computer and unplug the power cord.
