Using Firewall Software; Installing Critical Security Updates; Using Hp Client Security (Select Models Only) - HP EliteBook Folio 1040-G1 User Manual

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.
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 e-mail 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.
