  "description": "Ask Toolbar (historically tracked under detections including BrowserModifier:Win32/AskToolbar, Adware:Win32/AskToolbar, and PUA:Win32/AskPartnerNetwork) is a notorious browser add-on and search modifier produced by Ask.com / APN LLC. Widely bundled into consumer software installations—most notably historic Oracle Java Runtime Environment updates—the Ask Toolbar altered web browser configurations across Internet Explorer, Google Chrome, and Mozilla Firefox. It hijacked the user's default search provider, homepage, and error pages to direct traffic through Ask.com search portals. Additionally, it inserted promotional toolbars, displayed persistent sponsored banners, and collected detailed telemetry regarding user search queries and browsing habits to fuel advertising monetization.",
