How to remove YouTube Downloader (Virus Removal Guide)

YouTube Downloader by MagnusMentis Limited is recognized as a Trojan, Adware, and Potentially Unwanted Program (PUP) by antivirus programs including DrWeb and Webroot. YouTube Downloader is self-promoted as a tool for Windows XP, Windows Vista, Windows 7, Windows 8.1, and Windows 10 that allows users to download “any video, game play, news, music, and sports with no ads.” When launched, the program insists that users sign in to their YouTube accounts in order to use it.
