NEVER EVER,
EVER just click a link in an e-mail, expecially for banks/paypal/ebay sort of thing
just open up your web browser and enter the website, such as
https://www.paypal.com, if its important enough for them to email you about it, they will deffinatly give you a warning or a message when you log in normally, if not, its a hoax, 9 times out of 10, if you hover your mouse over the link, it will say something like "http://23.23.56.24/paypal.com/login.php" or some thing like that, which is deffinatly not how you get to paypal
so again, never click e-mail links randomly
