There is no need for you to be posting this download on here.. The bot would update itself if it wanted to, you wouldn't need a link in order to do so.
Just do yourself a favor and leave now.. Your not going to get anyone with this.
(and if your file wasn't so big and took so long to download, I would be scanning it right now and posting a screen shot of the outcome... which I'm still positive it will be infected..)
