Are you telling me that this is really from Facebook???? The video do what I do not want to do :(

Hi it is facebook malware. It's a facebook app that runs in your account. You probably enabled it without knowing it was malware. There are more videos on youtube with the same malware and how to remove it. And yes, it seems that you need to download the stuff to get rid of it.

hmmm Thanks a lot @cryptokas but I think I will not download this stuff, I am not so desesperate to go itno Facebook and I can do it in another computer... I think better will check the apps and desactivate what I do not use anymore first...lets see what happens :)

yes, since I'm a steemian I also spent less time on facebook. Well I have a group that I need to manage but thats it. hope you get it solved. grtz.
