Yahoo! Games is the section of the Yahoo! website in which Yahoo! users can play games either with other users or by themselves. The games on the website are typically Java applets or quick Flash games, but there are others which require a download. Many of the games that require a download contain TryMedia Adware (According to McAfee SiteAdvisor). Yahoo! Games also includes Yahoo! Video Games, which provides news, previews and reviews of currently available or upcoming First Party games–and Yahoo! Games on Demand–which provides free demos and full-size downloads of full PC games for a charge.
