What does it Do?
This is marketed as a way to add "skins" to your Internet Explorer and its toolbars. Most of the ads for this use babes in bikinis with large breasts or other things you'd want to stare out all day long. It would be perfectly fine if this program ONLY did this. The problem is it monitors every site you visit and displays advertisements in its toolbar that fit whatever site you're visiting.
