I am starting to think the safest browser is probably something written for Windoze 3.1
You won't get all those flash player movies and it won't autolaunch MP3 files but it also won't know what to do with most mal ware.
The decrepit old version of AOL I run can't open much on it's own anyway. I can look things over a bit before I launch them with the application I am comfortable with and most of the time it gets deleted before I even pull it out of my mailbox. Unlike Outleak it never downloads anything until you tell it to and I have it set to never launch anything I don't release.
