New virus on Facebook provides you change the design

No doubt Facebook will be in the coming years the most attacked the world, or at least that used by cyber criminals to perpetrate their acts, as in this new case in which you offer to change the design of your free Facebook but also what you get is a virus that will show you popup ads every time you browse.

The catch is that your friends also need to install the application to see changes in your profile, thus achieving a viral effect. So you know nothing of accepting and less weird if you ask for setting things up.
