Firewalls block certain types of communications between network devices. This helps protect your data from hackers, viruses, spyware, and Trojan horse software. The computer might have one or more firewall programs installed. For example, if the latest version of the Microsoft Windows XP operating system is installed, it is likely that the computer is using the Windows XP Firewall.
