IWon

IWon is an Internet web portal and search engine that offers users the chance to win money by earning entries in a sweepstakes. Entries are earned by performing the normal tasks performed on the Internet such as using search engines, checking ticker tape, reading email, and keeping up to date on the news.

Some spyware/malware programs like Spybot: Search & Destroy immunize computers against iwon.com so as to disallow visitation to the site.
