Remove LeadShared Adware from Mac

Mac users often assume their systems are immune to threats, but Potentially Unwanted Programs (PUPs) like LeadShared prove otherwise. This adware infiltrates macOS devices through deceptive methods and disrupts the user experience by displaying intrusive advertisements, tracking browsing activity, and potentially exposing users to security risks. While it may appear as a useful tool, its primary function is to generate revenue through aggressive advertising, often at the expense of user privacy and system performance.
