FLVTube is supposedly a video player that downloads and plays YouTube videos. Only a few anti-viruses categorize FLVTube as an adware, and most of the antivirus software do not have any detection for it. FLVTube uses the familiar fake codec download techniques
to trick PC users in downloading their software: You chance upon a video clip on a random website and to view it you need to download FLVTube! If FLVTube is really a genuine video player, then I wonder why they are using such misleading installation strategies.
