Using and understanding firewalls
A firewall can be hardware, software, or a combination of both depending on the level of security required.
Firewalls work on a set of rules to determine which inbound and outbound connections are authorized. If
your computer is preinstalled with a firewall program, it helps protect against computer Internet security
threats, unauthorized access, intrusions, and Internet attacks. It also protects your privacy. For more
information about how to use the firewall program, refer to the help system of your firewall program.
The Windows operating system preinstalled on your computer provides the Windows Firewall. For details on
using the Windows Firewall, refer to “Help and Support” on page 113.
Protecting data against viruses
Your computer is preinstalled with an antivirus program to help you guard against, detect, and eliminate
viruses.

30 days, you must renew the license to continue receiving the antivirus software updates.
Note: Virus definition files must be kept up-to-date to guard against new viruses.
