'Ice Sword', and 'Bug Me Not'

Ice Sword

IceSword is a sophisticated discovery tool that can protect against sinister rootkits if used before they infect a machine. It has a Windows Explorer-like interface but displays hidden processes and resources that Windows Explorer would never show.

Bug Me Not

Log in to numerous sites with these free web passwords to bypass compulsory registration. You're browsing the web and you click a link to an article on a site (let's say nytimes.com) but instead of getting the article you get a screen asking you to login or register. Infuriated at the idea of pointlessly registering for yet another site you turn to your good buddy bugmenot.com.
