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.
For more information about computer viruses, type viruses in the Search box in Help and Support.
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.
There are two types of firewalls to consider:
●Host-based firewalls—Software that protects only the computer it is installed on.
●Network-based firewalls—Installed between your DSL or cable modem and your home network to 
protect all the computers on the network.
When a firewall is installed on a system, all data sent to and from the system is monitored and compared 
with a set of user-defined security criteria. Any data that does not meet those criteria is blocked.
Your computer or networking equipment may already have a firewall installed. If not, firewall software 
solutions are available.
NOTE:Under some circumstances a firewall can block access to Internet games, interfere with printer or 
file sharing on a network, or block authorized e-mail attachments. To temporarily resolve the problem, 
disable the firewall, perform the task that you want to perform, and then reenable the firewall. To 
permanently resolve the problem, reconfigure the firewall.
Installing critical security updates
CAUTION:Microsoft® sends out alerts regarding critical updates. To protect the computer from security 
breaches and computer viruses, install all critical updates from Microsoft as soon as you receive an alert.
Updates to the operating system and other software may have become available after the computer left the 
factory. To be sure that all available updates are installed on the computer, observe these guidelines:
1.Run Windows Update as soon as possible after you set up your computer.
2.Run Windows Update monthly thereafter.
3.Obtain updates to Windows and other Microsoft programs, as they are released, from the Microsoft 
website and through the updates link in Help and Support.

HP Client Security software is preinstalled on select computer models. This software can be accessed 
through Windows Control Panel. It provides security features that help protect against unauthorized access 
to the computer, networks, and critical data. For more information, see the HP Client Security software Help.
Installing an optional security cable
NOTE:A security cable is designed to act as a deterrent, but it may not prevent the computer from being 
mishandled or stolen.NOTE:The security cable slot on your computer may look slightly different from the illustration in this 
section. See 
Getting to know your computer on page 4 for the location of the security cable slot on your
