If the 'Managed by your organization' entry appears in Chrome's main menu due to OptimumSearch or another unwanted app, it should be uninstalled immediately. OptimumSearch is a browser hijacker capable of setting and managing Chrome policies. The 'Managed by your organization' policies management feature allows administrators to install extensions, block access to various web pages, set the homepage address, disable the 'Print' feature, and control how browsers function in many other ways, however, these policies can also be managed by a browser hijacker or malicious app that users inadvertently install on the browser. In some cases, 'Managed by your organization' appears in browser settings due to an installed potentially unwanted application (PUA) such as a browser hijacker or malicious application. This feature is normally present on Chrome browsers that are managed by an organization or group, however, it is possible that regular users who do not have browsers controlled by an organization will also see this feature. 'Managed by your organization' is a Google Chrome feature (it can be found on the main menu) which allows administrators to manage browsers (set various policies) for users within their organization.
