HP Pavilion Dv7 4100 Entertainment Notebook Pc Series Manual

							Using antivirus software
When using the computer to access e-mail, a network, or the Internet, the computer is exposed to
viruses. Computer viruses disable the operating system, programs, or utilities, or cause them to function
abnormally.
Antivirus software detects most viruses, destroys them, and in most cases, repairs any damage caused.
To provide ongoing protection against newly discovered viruses, keep antivirus software up-to-date.
Norton Internet Security, an antivirus program, is preinstalled on the computer. The software includes
60 days of free updates. HP recommends protecting the computer against new viruses beyond 60 days
by purchasing extended update service. Instructions for using and updating Norton Internet Security
software and for purchasing extended update service are provided within the program. To view and
access Norton Internet Security, select Start > All Programs > Norton Internet Security.
For more information about computer viruses, type viruses in the Help and Support search box.
Using firewall software
When using the computer for e-mail, network, or Internet access, unauthorized persons might gain
access to the computer, your personal files, and information about you. Use the firewall software
preinstalled on the computer to protect your privacy.
Firewall features include logging and reporting of network activity, and automatic monitoring of all
incoming and outgoing traffic. For more information, see the firewall user guide or contact the firewall
manufacturer.
NOTE:Under some circumstances a firewall blocks access to Internet games, interferes with printer
or file sharing on a network, or blocks authorized e-mail attachments. To temporarily resolve the
problem, disable the firewall, perform the task, and then reenable the firewall. To permanently resolve
the problem, reconfigure the firewall.

							11 Troubleshooting
Cannot connect to a WLAN
Before troubleshooting a network connection problem, be sure that device drivers are installed for all
wireless devices.
NOTE:Wireless networking devices are included with select computer models only. If wireless
networking is not listed in the feature list on the side of the original computer package, add wireless
networking capability to the computer by purchasing a wireless networking device.
Possible causes for wireless connection problems include:
●Changing the network configuration (SSID or security)
●Disabling or incorrectly installing the wireless device
●Failing wireless device or router hardware
●Encountering interference from other devices
If you have a problem connecting to a WLAN, confirm that the integrated WLAN device is properly
installed on the computer:

Current network security codes are unavailable
If prompted for a network key or a name (SSID) when connecting to a WLAN, the network is protected
by security. Enter the current codes to make a connection on a secure network. The SSID and network
key are alphanumeric codes that are entered to identify the computer to the network. To find the codes:
●For a network connected to your personal wireless router, review the router user guide for
instructions on setting up the same codes on both the router and the WLAN device.
●For a private network, such as a network in an office or at a public Internet chat room, contact the
network administrator to obtain the codes, and then enter the codes when prompted.
Some networks change the SSID or network keys used in their routers or access points on a regular
basis to improve security. Change the corresponding code in the computer accordingly.
