Using and understanding rewalls
A rewall 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 rewall 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 rewall program, refer to the help system of your rewall 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 73
.
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 denition les must be kept up-to-date to guard against new viruses.
