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.
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.
