    							8 Securing your computer and
    information
    Computer security is essential for protecting the confidentiality, integrity, and availability of your
    information. Standard security solutions provided by the Windows operating system, HP applications,
    the non-Windows Setup Utility (BIOS), and other third-party software can help protect your computer
    from a variety of risks, such as viruses, worms, and other types of malicious code.
    IMPORTANT:Some security features listed in this chapter may not be available on your computer.
    Computer risk Security feature
    Unauthorized use of the computer Power-on password
    Computer viruses Antivirus software
    Unauthorized access to data Firewall software

    other system identification informationAdministrator password
    Ongoing or future threats to the computer Software updates
    Unauthorized access to a Windows user account User password
    Unauthorized removal of the computer Security cable lock
    Using passwords
    A password is a group of characters that you choose to secure your computer information and to
    protect online transactions. Several types of passwords can be set. For example, when you set up
    your computer for the first time, you were asked to create a user password to secure your computer.
    Additional passwords can be set in Windows or in the HP Setup Utility (BIOS) that is preinstalled on
    your computer.
    You may find it helpful to use the same password for a Setup Utility (BIOS) feature and for a Windows
    security feature.
    Use the following tips for creating and saving passwords:
    ●To reduce the risk of being locked out of the computer, record each password and store it in a
    secure place away from the computer. Do not store passwords in a file on the computer.
    ●When creating passwords, follow requirements set by the program.
    ●Change your passwords at least every three months.
    ●An ideal password is long and has letters, punctuation, symbols, and numbers.
    ●Before you send your computer for service, back up your files, delete confidential files, and then
    remove all password settings.
    For additional information about Windows passwords, such as screen-saver passwords, from the
    Start screen, type support, and then select the HP Support Assistant app.

    computer to computer viruses, spyware, and other online threats. To help protect your computer,
    Internet security software that includes antivirus and firewall features may be preinstalled on your
    computer as a trial offer. To provide ongoing protection against newly discovered viruses and other
    security risks, security software must be kept up to date. It is strongly recommended that you upgrade
    56 Chapter 8   Securing your computer and information 
    						
    							the security software trial offer or purchase the software of your choice in order to fully protect your
    computer.
    Using antivirus software
    Computer viruses can disable programs, utilities, or the operating system, 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.
    An antivirus program may be preinstalled on your computer. It is strongly recommended that you use
    the antivirus program of your choice in order to fully protect your computer.
    For more information about computer viruses, from the Start screen, type support, and then select
    the HP Support Assistant app.
    Using firewall software
    Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be
    software you install on your computer and/or network, or it can be a combination 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.
    Installing software updates
    HP, Microsoft Windows, and third-party software installed on your computer should be regularly
    updated to correct security problems and improve software performance. For more information, see
    Updating programs and drivers on page 52.
    Installing critical security updates
    HP recommends that you regularly update the software and drivers that were originally installed on
    your computer. To download the latest versions, go to 
    http://www.hp.com/go/contactHP. At this
    location, you can also register to receive automatic update notifications when they become available.
    If you have installed third-party software after you purchased your computer, regularly update the
    software. Software companies provide software updates to their products to correct security problems
    and improve functionality of the software.
