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.
Windows Defender is preinstalled on your computer. It is strongly recommended that you continue to use an
antivirus program in order to fully protect your computer.
For more information about computer viruses, access the HP Support Assistant.
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.
