Microsoft announced on Tuesday the general release of its free anti-spyware program, a move that significantly steps up the software maker’s competitive challenge in the security industry.

Windows Defender anti-spyware is now available in English to Windows XP users, with other languages set for delivery in coming weeks. Windows Defender will also be bundled with Windows Vista, Microsoft’s next-generation operating system, when it is released in January.
