Windows 7 features: security and security - Windows Firewall

Windows Firewall helps you protect your computer from hackers and malware. In Windows 7, this feature is still very powerful, but it's more flexible and easier to use.

For example, you can now fine-tune the protection and notification features you need for each network profile (home, office, and public). In the past, when you connected to a public network, such as a library or coffee shop, you might need to interrupt all incoming connections. At home or at work, this is a bit of a laborious move. Now, no matter what level of protection you choose for your profile, you will be able to easily switch between profiles.

Windows Firewall provides tailored protection for different network environments.
