• Administrator Password: Setting an Administrator Password deters unauthorized users from changing
configuration settings. If you are responsible for maintaining the configuration settings of several
computers, you might want to set an Administrator Password. For more information, see “Administrator
Password” on page 90.
You do not have to set any passwords to use your computer. However, using passwords improves
computing security.
Windows passwords
Depending on your version of the Windows operating system, you can use passwords for a variety of
features, including controlling login access, access to shared resources, network access, and individual user
settings. For more information, see “Help and Support” on page 119.

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 preintalled 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 119.
Protecting data against viruses
Your computer is preinstalled with an antivirus program to help you guard against, detect, and eliminate
viruses.
Lenovo provides a full version of antivirus software on your 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.
