The Security Center

Use the Security Center to check your security settings and learn more about how to improve the security of your computer with Windows Firewall, Automatic Updates, and antivirus software.

Windows Firewall

Windows Firewall is on by default and helps protect your computer against viruses and other security threats, such as intruders who might try to access your computer over the Internet.

Automatic Updates

With Automatic Updates, Windows can routinely check for the latest important updates for your computer and install them automatically.

The pop-up blocker in Internet Explorer

The Internet Explorer Pop-up Blocker lets you stop most browser windows that Web sites pop up without your permission, giving you more control over your Web browsing experience.

Outlook Express

Enhanced security settings help you identify and delete potentially harmful e-mail attachments, which can contain viruses.
