It's a scam (pretty sophisticated one at that).
You prompted me to check my PayPal and it opens with this message..........
"* PayPal emails will never ask you for personal information such as social security numbers, passwords, credit card or bank account numbers"
"Never Give Out Personal Information
Keep your PayPal account safe and secure; here are some tips every PayPal member should know:
* Log in safely whenever you access your PayPal account; open a new web browser (e.g. Internet Explorer or Netscape) and type in the following: https://www.paypal.com.au
* PayPal emails will never ask you for personal information such as social security numbers, passwords, credit card or bank account numbers
* Never download any attachments in a suspicious email
If you think that you have received a fraudulent email (or fake website link in an email), please forward the email (or URL address) to [email protected] and then delete the email from your mailbox. Visit our Security Centre to learn more."
