So someone was asking me about download youtube videos and / or audio from youtube videos. Since I had the time, I did a quick search on google and found that there's a simple application to get this done. Be it, you will have to copy the youtube url to the application, its still free and fairly easy to use.
You can get Free Youtube Download via http://youtubedownloader.com/
It is also available via CNET's Download.com Website
AVG 2014 reported that it was virus free
