I haven't a clue what win32:Tiny-ES is but it has been stopped by the web shield (abort connection stops the download of the file) so it isn't or shouldn't be on your system.
You could try a google search for win32:Tiny- (like I did), which would bring up more about the win32:tiny family), the problem is there is no standardisation on malware naming so it may be different in other AV names. This however, appears to be a trojan downloader (but there are many variants) that if on your system attempts to download either more malware or spyware, etc. So you are better off without it.
YouTube can be exploited with stuff like this as what is on the actual page isn't infected it is only when you load something else from another source and it is possible to have a link not only load a flash (which can be exploited, so you need to have the latest flash player updates) but something else.
