Protect 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, your computer, and your data.

To optimize the privacy protection features included with the

computer

■� Keep the operating system and software updated. Many

software applications contain security enhancements.

■� Use a firewall. A firewall is software that monitors incoming

traffic on the computer. Some firewalls also monitor outgoing

traffic.

Protect the computer from power surges

To protect the computer from the power surges that might be

caused by an uncertain power supply or an electrical storm:

■� 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.

■� If applicable to your location, provide surge protection on the

modem cable that connects the modem to a telephone line.

Telephone line surge protectors are available from computer

or electronic retailers in some regions.
