Their Twitter is being flooded with complaints but DivX does not appear to care. In there latest update on Mac when clicking Ok the last page of the setup briefly shows a message about Bing but them immediately finishes the installation without allowing user interaction. After that your Chrome, Safari and Firefox will be flooded with Bing. From 404s, homepage, default search and conduit plugins. The link above shows the numerous steps to undo all of it. The one step they forget to mention is to uninstall DivX and never use them again. Even Google Chrome is marking DivX as Malware which DivX is saying is a false positive to ignore. Please everyone uninstall DivX and let them know malware is never acceptable.
