Watch Out Guys.
Just found a tweet from Myetherwallet Official Twitter Page that states as follows
Couple of DNS servers were hijacked to resolve http://myetherwallet.com users to be redirected to a phishing site. This is not on @myetherwallet side, we are in the process of verifying which servers to get it resolved asap.
Please donot use Myetherwallet , till the time you get confirmation from the MEW Team that its All safe to continue.
