OpenCandy from SweetLabs, Inc., a company based in San Diego, is an advertising software module consisting of a Microsoft Windows library that can be incorporated in a Windows Installer. When a user installs an application that has the OpenCandy library, there is an option to install additional software that it recommends (based on a scan of the user's system and geolocation).
The software was originally developed for the DivX installation, by CEO Darrius Thompson. When installing DivX, the user was prompted to optionally install the Yahoo! Toolbar. DivX received $15.7 million during the first nine months of 2008 from Yahoo and other software developers, after 250 million downloads.
OpenCandy has attracted criticism because of privacy concerns. Past versions of OpenCandy were considered adware by Microsoft Security Essentials as they "may send user-specific information ... without obtaining adequate user consent". OpenCandy have claimed that this is because another company used OpenCandy without the formal warning in their EULA.
