Okay, those who are clicking the link below need to realize it's malware. If you look at every video posted recently that link (or something very similar) keeps getting posted by different people. That's how it works, it is trying to infect as many people as possible. If you have clicked it or pasted it into your url, do a system restore to a recent restore point, use windows defender (may not detected it), use windows malwarebytes (you have to download that through microsoft), or just do a complete system wipe and reset. There are other options as well.. but take a bit more know how.
Cheers
