Windows Defender home: This been a long road. Microsoft bought Giant Antispyware, then engaged in some semi-sleazy tactics to get someone to give up the name “Windows Defender.” And here it is, finally.
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.
It’s a good product, actually. I use it on a lot of machines, and it’s one of my first tools to fix a crapped-up install.
