18 Getting Started (features vary by model)
Using antivirus software
When you use the computer for e-mail, network, or Internet access, you expose it to computer
viruses. Computer viruses can disable or damage the operating system, software programs,
or computer utilities.
Antivirus software can detect most viruses, remove them, and, in most cases, repair any
damage that they have caused. To provide ongoing protection against newly discovered
viruses, you must keep the antivirus software up to date.
The antivirus program, which is preinstalled on the computer, includes antivirus and firewall
components. The software includes a free trial subscription of protection updates. To protect
the computer against new viruses beyond the trial period, purchase an extended update
service. Instructions for using and updating the antivirus software, and for purchasing
extended update service, are provided within the program.
For more information about computer viruses: Click the Start button, click Help and
Support, and then type viruses into the Search Help box and press Enter. See “Using the
Help and Support Center” on page 25.
Using firewall software
When you use the computer for e-mail, network, or Internet access, unauthorized persons
may be able to gain access to information about you, your computer, and your data. To
protect your privacy, use firewall software:
Windows 7 includes firewall software preinstalled on the computer.
The antivirus program, which is preinstalled on the computer, includes a firewall
program.
Firewall features include logging, reporting, and automatic alarms to monitor all incoming
and outgoing communications.
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 solve the
problem temporarily, disable the firewall, perform the task that you want to perform, and then
enable the firewall again. To resolve the problem permanently, reconfigure the firewall.
Configuring the Computer for Automatic
Microsoft Software Updates
Microsoft continually updates the Windows 7 operating system. Run Windows 7 Update
monthly to install these updates, or keep the operating system up to date by using the
Automatic Updates feature.
When you are connected to the Internet, Windows 7 Update automatically notifies you
(through a pop-up message or icon in the notification area) when critical updates are
available. When you see the Windows 7 Update message, allow the updates to download to
your system. If you update the system weekly, or even monthly, the time required for
download is minimal.
