Using antivirus software
When you use the computer to access e-mail, a network, or the Internet, you potentially expose it to
computer viruses. Computer viruses 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 any damage they
have caused. To provide ongoing protection against newly discovered viruses, antivirus software
must be kept up to date.
An antivirus program may be preinstalled on your computer and may include a trial offer. It is strongly
recommended that you upgrade the trial offer or purchase the antivirus program of your choice in
order to fully protect your computer.

Using firewall software
Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be a
software program you install on your computer and/or network, or it can be a solution made up of
both hardware and software.
