If you receive an e-mail like this:
Your Apple ID will be disable because of some violated policies.
You need to sign and verify it as soon as possible. (we have noticed that
your account information appears to be invalid and unverified).
Please open the attached file and verify your apple id before 24 hours, or
your apple id will be disable permanent.
Do NOT open the attachment and do NOT respond to it. This is a third party forging an e-mail to look like Apple but it is NOT Apple and if you respond to this you will be giving a third party your Apple ID with which they can make purchases.
