Windows Security

Windows Security Center can help enhance your computer’s security by checking the status of several security essentials on your computer, including firewall settings, Windows automatic updating, anti-malware software settings, Internet security settings, and User Account Control settings. If Windows detects a problem with any of these security essentials (for example, if your antivirus program is out of date), Security Center displays a notification and places a Security Center icon Picture of the red Security Center shield

Firewall

A firewall can help prevent hackers or malicious software (such as worms) from gaining access to your computer through a network or the Internet. A firewall can also help stop your computer from sending malicious software to other computers.Windows checks if your computer is protected by a software firewall.
