It is a set of related programs configured to protect private networks connected to the Internet from intrusion. It regulates the network traffic between different computer networks.

Windows Defender is a software product from Microsoft to prevent, remove and quarantine spyware in Microsoft Windows. It was formerly known as Microsoft AntiSpyware. It is included and enabled by default in Windows Vista and Windows 7, and is available as a free download for Windows XP and Windows Server 2003.

Windows Defender features system scan capabilities similar to other free products on the market, and includes a number of real-time security agents that monitor several common areas of Windows for changes which may be caused by spyware. It also includes the ability to easily remove ActiveX applications that are installed. If it detects anything suspicious, an alert will appear on the screen.

1. Protected mode: The protected mode feature of IE 7+ prevents a computer from saving the files or programs of a Web site. Protected mode makes it more difficult for malware to be installed.

Protected mode is enabled by default for Internet, local intranet, and restricted sites. However, it is not enabled for trusted sites.

1. User Account Control: User Account Control (UAC) is a security feature introduced with Microsoft’s Windows Vista operating system. It helps in preventing unauthorized changes to a user’s computer. UAC asks the user for permission or an administrator password before performing actions that could potentially affect a computer’s operation or that change settings that affect other users. It improves the safety and security of the computer by preventing harmful programs from making changes to the computer. This feature works with Windows Defender and Internet Explorer 7 to help reduce the impact of viruses, spyware, and other threats.
