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 HP Support Assistant. To access HP Support
Assistant on the Start screen, select the HP Support Assistant app.
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.
