Watch your email.  Do not open an email that says your passwords have been reset.  They are phishing for sensative, private information such as your banking information.

These are coming to your personal email, not to your facebook messages. It reportedly will also attack your computer rendering it useless.

Be aware.  Don't fall for this one.
