Firewalls work on a set of rules to determine which inbound and outbound connections are authorized. If the
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.

viruses.
Lenovo provides a full version of antivirus software on the computer with a free 30-day subscription. After 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.
