I received similar e-mails too.

I wouldn't want to frighten you, but I think that it's better that people should be aware of the phenomenon called
"social engineering" as well. This complex method includes phishing and is used mostly by hackers to obtain private information (name, address, credit card numbers, bank accounts, passwords etc.)
How does it work?1. Let's say you create an account on a OnlineGameWebsite using your e-mail address (some people use the same address to log into their PayPal account).
2. After completing the registration form you must choose a password (most of us have the same password on more than one account).
3. a) The OnlineGameWebsite database containing all e-mail addresses and passwords are used by the owner of that website to log into different payment processor accounts (PayPal, Payza etc.)
or
3. b) If the website is not properly protected, someone gains access to the database of the OnlineGameWebsite and uses that information to log into different payment processor accounts.
But don't panic, because there are a few ways to
protect yourself from becoming a victim of social engineering:
1) Install an Antivirus program. If you don't want to purchase one, you can use one of these that can be downloaded for free: Avast, Panda Cloud or Microsoft Security Essentials.
2) Don't use the same password on more than one accounts.
3) Change your passwords frequently (15-30 days).
4) Note down your passwords on a piece of paper, don't store them in a document on your PC.
