Anyone know about the new Facebook scam, "99% of people stop watching this after 25 second?"?

Anyone know about the new Facebook scam, "99% of people stop watching this after 25 second?"?

Well, like the dumb idiot that I am (that is redundant) I clicked on a link my friend had posted because it said it was from Youtube… so I believed it was legitimate and now I am worried that I might be hacked and possibly have to scan my computer for keyloggers?
When I clocked on the link it sent me to a page that told me to do a survey for Wal-mart(to win something) and see the video.
Any advice? Thanks.
