What is GreyGray?

GreyGray is a potentially unwanted web browser extension that is designed to deliver search-based hijacking/injection as well as contextual advertising. The program does this by modifying the user's home and search page in order to monetize a user's search activities. By installing a Browser Helper Object (BHO) in Internet Explorer, the extension has the ability to monitor and track a user web browsing activities and display various banner and link-context ads in addition to its search redirection.

From the EULA: "Default search engine and home page settings may be adjusted. Search engine results will open in a new browser tab window when clicked. Predictive (instant) search engine results are not displayed. Enables both HTTPS (encrypted with SSL/TLS protocol) content and HTTP (unencrypted) content on a webpage without first alerting the user and obtaining consent."
