WARNING: Changing your Yahoo! account password is NOT enough to regain control of your account!

There’s an insidious hack you need to check on immediately — whether a hacker has changed your settings to auto-forward all your email to another address he controls. He doesn’t care whether you’ve changed the password, if all your email is going to be auto-forwarded to him! In fact, he hopes that you regain confidence in your Yahoo! email and continue using it.
