Yes, this has happened a couple times to me in the past... way before I installed Mobile Trust/Guarded ID. Facebook will usually guide you through the process of helping you change your password and logout of all locations. Another thing that may help (but is sometimes a pain) is to set-up it's version of two-factor authentication. When you try to login to fb on your computer, it will send your fb phone app a code... enter the generated code on your computer and you're in. I have no idea if this infringes on Strikeforce patents. All I know is that ever since I installed MT/GID, changed my passwords, and added the 2FA... I haven't been re-hacked ever since! Good luck, Caruso!
