Donot install the fake plugins from the fake blogs or website after being redirect by fb video ads. These are not the videos actually images with the hyperlink. Actually if you click on a fake add or video it redirect you onto other website and tells you to install the plugin for watching this video. This is totally fake thing. If u install the plugin, it will send this fake video or add message to all of your friends.
Actually it contains a loop that send message to all of your friends. So we aware.
