But this one is specifically for visiting porn sites with. It’s called Heatseak and implements a shell on IE, closing it down for much of the nasty behaviour certain porn sites exhibit (spyware, popups etc). The installer allows you to choose a variety of names / icons for it, so it’s not too obvious on your PC, and it has playlists of the stuff you’ve downloaded a bit like itunes. Also all the downloaded content and sites you’ve visited are stored encrypted on its’ own bit of disk, so no one else can get at it or see where you’ve gone. Anonymity is a big point of the design. If you want to view the content outside of Heatseak you pay $20,- for a gold version.
