Protect Your Personal Data on the Internet
Your self-defense is to check a domain name using the WHOIS program, www.nsi.com. Type in the site’s Web address to see who operates it. If details do not match those of the legitimate site you wanted to visit, then you should not entertain that email, or stay away from it. One important thing also is to use Mozilla Firefox browser to which you have to check the website concern's SQL (you can do it by hovering your mouse to the circle just on the left side near of URL, if it says " This website does not supply identity information" then, you must be alarmed!

Only today, my dearie friend told me that she has an email from Paypal and was asking her to update her bank information or credit card information. Good thing, she knows it is not the legit PayPal. So, what she did was forward the email to PayPal, and had a great reply from them. They thanked her for forwarding that email and they told her that they would definitely investigate who operate such kind of Internet Mail (email).
So, be alarmed! Be cautious and exercise your guts and instinct! We know that our world is full of trickery, so be wary (or else you'll be sorry)!
