All I wanted for Christmas was a Secure way to browse the web.
Wait, I already have one... and better, it's Freeware!
I've been using it for a little while, and have been very satisfied with the operation of Kace's Secure Browser (it's essentially a Sandboxed Firefox 3.6 Browser with Adobe Reader and Flash plug-ins). It keeps your computer from getting sick when the occasional teenager decides to hop on your computer and the next thing you hear is "All I did was check my FaceBook Page!"
You can pick it up from Kace's Website Here.
