  "description": "GoTango (classified as BrowserModifier:Win32/GoTango and Adware:Win32/GoTango across Microsoft Defender, Malwarebytes, and Trend Micro) is an aggressive browser modifier and adware toolbar bundled with freeware downloads and deceptive online media converters. Once executed, GoTango silently modifies browser configurations across Chrome, Firefox, and Internet Explorer without user consent. It changes the default search provider, start page, and new tab URLs to ad-supported portal domains (such as search.gotango.com). It hooks browser network sockets to intercept search queries, inject sponsored links and pop-up ads into browsing sessions, and collects user navigation history and hardware telemetry for monetization. GoTango creates autostart registry entries and persistent background updater services to resist manual uninstallation.",
