If you are going to engage in unsafe browsing, best not be an administrator.

I agree with the point about  running as an Administrator  (although for Windows users that means you're either running a crippled system that won't install or run a variety of software, especially games, in "User Mode" on XP, or you're compelled to upgrade to Vista)

But I believe that labeling browsing as "Unsafe" can be a bit of a distinction without a difference.  Consider:

AOL, Facebook, Geocities, Google’s Blogspot and Google Pages, and Rapidshare, Hubbard said.

Most of the Web sites either hosted malicious content or silently redirected visitors from trusted pages to hostile sites. Hubbard said the redirect most favored by attackers is at DoubleClick, one of the Internet's largest online ad companies

LOL. I wouldn't go to most of these sites from a business computer, and at home I would be on my toes.

Spyware Blaster puts doubleclick and a thousand other ad servers in the restricted zone. You will never request anything from them.
