Using antivirus software

When you use the computer to access email, 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 email 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.
