What is GreyGray?

This is a variant of the Web Cake adware. It is a web browser extension that will modify the user's home and search providers as well as display contextual and popup advertising in the browser. Once installed the software will add a number of unwanted features to the web browser including inline text and multi-site searching, comparison shopping, related search results, additional offers and coupons as well as website ratings and reviews. It does this by analyzing the content of the web pages the user is visiting as well as tracking the URLs and navigation. Additionally GreyGray will add features as desired after install through its 'auto-enabled updater' which runs as a service.
