What Is Campaign Notifier Extension?
Campaign Notifier (ID: bgoclljmbknlgpbpcnbggokjpdgmcfga) is a browser extension for Chrome that plays sound ads in the background. It may appear on your browser after you install some free program or run a file downloaded from a questionable source (torrents, sites offering pirated content, etc.). Campaign Notifier is harder to remove than most other rogue extensions, as the Remove button for the extension is missing on the Extensions page. That is because Campaign Notifier changes Group Policy for Chrome to make itself “installed by administrator”. Group Policy is something intended for admins of corporate networks and allows them to manage settings and programs on users’ computers. You may follow this step-by-step guide to reset Group Policy and remove Campaign Notifier from Google Chrome.
