Norton 360 now kills Youtube downloader

I've been using Youtube Downloader since forever. When I need to update or reinstall I always make sure I decline the included crapware. Now, just as of today,  Norton 360 is removing Youtube Downloader and also stops it from completing a fresh install. I am getting a Norton 360 warning that YoutubeGTapp has been detected and blocked. Can anyone tell me how to make Norton 360 ignore this problem and let Youtube Downloader complete it's install and run?
