Microsofts AntiSpyware Beta has been comletely revamped with many bug fixes and improvements, along with a new name, Windows Defender.

Windows Defender (Beta 2) is a free program that helps protect your computer against pop-ups, slow performance, and security threats caused by spyware and other unwanted software. It features Real-Time Protection, a monitoring system that recommends actions against spyware when it’s detected, and a new streamlined interface that minimizes interruptions and helps you stay productive.

Windows Defender is free but requires an authentic installation of Windows in order to install.
