Facebook Register This Computer
Click at the image above and see it in details. This is the email I received and my FaceBook account was recently hacked. I recovered it in few attempts (Genius). But here is a caution for everybody.

So do not open attachments containing files with Facebook name in that or something like ‘Facebook_Password_3eb0e.zip‘ or ‘Facebook_Password.zip‘.
