Overview

Windows Defender is based on GIANT AntiSpyware, which was originally developed by GIANT Company Software, Inc. The company's acquisition was announced by Microsoft on December 16, 2004. While the original GIANT AntiSpyware supported older versions of Windows, support for the Windows 9x line of operating systems was dropped. However, Sunbelt Software, which was originally GIANT's partner, sells a product based in the same technology called Counterspy which still has support for older Microsoft operating systems.

Microsoft's upcoming Windows Vista operating system will also have Defender included as an integrated part of the operating system, and will be enabled by default.

Windows Defender not only features scanning of the system similar to other free products on the market, but also 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. Also integrated is support for Microsoft's SpyNet™ network, that allows users to report to Microsoft what they consider to be spyware, and what applications and device drivers they allow to be installed on their system.

Beta 1

The first release of Microsoft AntiSpyware was released in beta form on January 6, 2005 and was basically a repackaged GIANT AntiSpyware. It was then a free product (though only for genuine installations of Windows) and the word GIANT disappeared from the product. Few new features were added over the GIANT product; it was mainly a temporary re-branding release until it could be rewritten and rebranded. More builds were released as 2005 progressed, with the last Beta 1 refresh released on November 21, 2005.

Beta 2

Windows Defender (Beta 2) was released on February 13, 2006. It featured the program's new name and a significant redesign, resulting in huge improvements. The core engine was rewritten in C++, unlike the original GIANT-developed one, which was written in Visual Basic [1]. This improved the performance of the application. Also, the program now works as a Windows service, unlike the earlier release, which enables the application to protect the computer even when a user is not logged on. Because of this, the Windows Defender application is technically an interface to the service, which is also called by the same name. In addition, the application now protects more points-of-entry than the original application, while providing a more streamlined and intuitive interface. Beta 2 also requires Windows Genuine Advantage validation. However, Windows Defender (Beta 2) did not contain some of the tools found in Microsoft AntiSpyware (Beta 1). This consists of removed functionality of the System Explorer tool found in MSAS (Beta 1) and the Tracks Eraser tool, which allows the user to easily delete many different types of temporary files found in Windows, including cookies, temporary internet files, and Windows Media Player playing history.

RTM

On October 24, 2006, Microsoft announced the final release of Windows Defender.[1] It supports Windows XP and Windows Server 2003; however, unlike the betas, it does not support Windows 2000. Support for Windows 2000 was cut because at the time of RTM release, Windows 2000 was considered not to be "a popular consumer operating system" and had reached the end of its mainstream support period.[2] Windows XP is a line of operating systems developed by Microsoft for use on general-purpose computer systems, including home and business desktops, notebook computers, and media centers. ...

Real-time protection

In the Windows Defender Options you can configure the Real-time Protection options: Adware blocked by real-time protection on Windows Defender Real Time Protection is a feature of many anti-spyware programs which monitor computer systems for suspicious activity such as spyware, adware and other malicious objects in real-time ie while surfing the web. ...

IE integration

There is integration with Internet Explorer which enables files to be scanned when they are downloaded to help ensure that one does not accidentally download malicious software. This implementation is similar to the real-time scanners of many Anti-Virus products on the market. Windows Internet Explorer, previously Microsoft Internet Explorer, abbreviated IE, or MSIE,[1] is a graphical web browser developed by Microsoft and included as part of the Microsoft Windows line of operating systems. ... Anti-virus software consists of computer programs that attempt to identify, thwart and eliminate computer viruses and other malicious software (malware). ...


Software explorer

The Advanced Tools section allows users to discover potential vulnerabilities for themselves with a series of "Software Explorers". In Beta 1, users were able to browse downloaded ActiveX controls, running processes or Startup programs, Internet Explorer BHOs, settings or Toolbars, the Windows hosts file, Winsock LSPs or Shell Execute Hooks. Windows Defender has removed some of this capability, only providing views of startup programs, currently running software, and Windows sockets providers (Winsock LSPs). The explanation given for removing the ActiveX controls and Tracks Eraser functionality is that that functionality is now found in Internet Explorer 7. In programming, the Component Object Model (COM), also known as ActiveX, is a Microsoft technology for software components. ... Add-on Manager from Windows XP SP2 Internet Explorer A Browser Helper Object (BHO) is a DLL module designed as a plugin for Microsofts Internet Explorer web browser to provide added functionality. ...

In each explorer, every element is rated as either "Known", "Unknown" or "Potentially Unwanted".

SpyNetâ„¢ is a voluntary worldwide community of Windows AntiSpyware (formerly name of Windows Defender) or Windows Defender users that helps to determine which suspicious programs are classified as spyware. ...


Browser restore

The Browser Restore feature, a component of the previous version Microsoft AntiSpyware, allowed users to restore all or some of Internet Explorer's settings such as the default search engine back to the defaults. This will sometimes revert the changes made by browser hijackers, though further action is sometimes required. Windows Internet Explorer, previously Microsoft Internet Explorer, abbreviated IE, or MSIE,[1] is a graphical web browser developed by Microsoft and included as part of the Microsoft Windows line of operating systems. ...

Erase tracks

Microsoft AntiSpyware (Beta 1) contained a track erasing feature which could erase the usage history for various Microsoft and third-party applications. The extent to which such items are really erased is not documented. This feature however, was removed in Beta 2 and is unlikely to return.

Windows Vista specific functionality

Windows Defender in Windows Vista automatically blocks all startup items that require administrator privileges to run (this is considered a bad behaviour for a startup item). There is no known easy way to automatically unblock these items, the only suggestion given is to "contact the software vendor for an updated version" which is Vista compatible (does not require administrator privileges to run). This automatic blocking is related to the UAC (User Account Control) functionality in Windows Vista, and requires the user to manually run each of these startup items each time they log in. If there is no updated version of the startup item, the only currently known way to circumvene this behavior is to disable UAC altogether (since this is also a UAC related functionality, disabling Windows Defender while not disabling UAC will not solve the issue).


Controversy over name

There is some controversy over the name "Windows Defender" which was acquired from a company supplying software under the same name.[3] Microsoft claims that it is protecting the term "Windows" as their trademark.

Windows Defender Beta 2 - Security - Network Computing (697 words)
Windows Defender offers a new detection-and-removal spyware engine, an increased number of Windows monitoring points it watches for possible spyware symptoms, a heavily streamlined user interface, fewer pop-ups from its real-time protection asking for user input, and protection for all Windows user accounts.
Windows Defender will also be included in Windows Vista, and first made an appearance there in the December CTP version.
It might also be related to the Windows Defender Beta 2 pre-release software I was given (which was not widely distributed), because I have not heard widespread complaints.
