Why pay a small fortune for Microsoft Office when you can get a word processor, spreadsheet editor, and presentation maker for free?

Okay, but which sites are safe and which ones are potentially dangerous? That's the question answered by Site Advisor, which adds a kind of red-light/green-light filter to your Web browser.
