Has to be a bad download. It should only be 2.8GB's according to the website. I remember once long long ago I had downloaded an image file of something and its reported size too was outlandish. I think it may have been a zipbomb, (not that its what's you have) but basically its an old trick that some do to compressed files that have compressed files within and are filled with 0's So when someone tries to uncompress it boom! You prolly just had a bad download.
