Five days after releasing the final version of Internet Explorer 7.0, Microsoft has struck again, this time with the first official release version of its free spyware removal application. Dubbed Windows Defender, the app was in beta testing for close to two years and is based on Giant AntiSpyware, a third-party spyware removal tool Microsoft purchased in late 2004. Windows Defender offers a variety of features in addition to standard spyware scanning and removal, including scheduling, real-time monitoring/protection, and automatic updates. Microsoft is only offering the software in English for Windows XP at the moment. However, the company intends to add multi-language support in the coming weeks and to bundle the app with Windows Vista when the new operating system is released next January.
