Windows Security Center
Windows Security Center helps make your PC secure by alerting you when your security software is out of date or when your security settings should be strengthened. The Security Center displays your firewall settings and tells you whether your PC is set up to receive automatic software updates from Microsoft.
Windows Security Center also shows the status of software designed to protect against spyware, your Internet Explorer 7 or Internet Explorer 8 security settings, and User Account Control. In addition, Windows Security Center can monitor security products from multiple companies and show you which are enabled and up to date.
