There is a new ongoing MEW phishing attempt. Please do not visit it, as you risk accidental visits in the future from URL bar autosuggest. ALWAYS DOUBLE CHECK EVERYTHING, PARTICULARLY A URL
Running MyEtherWallet locally is always more secure. There's also a Chrome plugin
The REAL URL of MyEtherWallet does not have an appended .co
The url of the phishing attempt is: myetherwallet (dot) com (dot) co
It's a very convincing phishing attempt. Again, DO NOT VISIT THAT LINK. IF YOU HAVE, IT IS SUGGESTED TO CLEAR BROWSING HISTORY
++++++++
Consider taking a minute of your time to report the phishing site to Google, the more that do, the more likely Google will pay attention. If they pay attention, Chrome users would be displayed a phishing alert, mitigating a large majority of potential damage.
