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 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 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 software updates
HP, Windows, and third-party software installed on your computer should be regularly updated to correct
security problems and improve software performance.
IMPORTANT: Microsoft sends out alerts regarding Windows updates, which may include security updates.
To protect the computer from security breaches and computer viruses, install all updates from Microsoft as
soon as you receive an alert.
You can install these updates automatically.
To view or change the settings:
1. Select the Start button, select Settings, and then select Update & Security.
2. Select Windows Update, and then follow the on-screen instructions.
3. To schedule a time for installing updates, select Advanced Options, and then follow the on-screen
instructions.
