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 rewall software

Firewalls are designed to prevent unauthorized access to a system or network. A rewall 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 rewalls to consider:

●

Host-based rewalls—Software that protects only the computer it is installed on.

●

Network-based rewalls—Installed between your DSL or cable modem and your home or oice network

to protect all the computers on the network.

When a rewall is installed on a system, all data sent to and from the system is monitored and compared with

a set of user-dened security criteria. Any data that does not meet those criteria is blocked.

Your computer or networking equipment may already have a rewall installed. If not, rewall software

solutions are available.

NOTE: Under some circumstances a rewall can block access to Internet games, interfere with printer or le

sharing on a network, or block authorized e-mail attachments. To temporarily resolve the problem, disable

the rewall, perform the task that you want to perform, and then reenable the rewall. To permanently

resolve the problem, recongure the rewall.

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:
