www.5dd.com opens in Chinese

Whenever I enter a Microsoft Office 2010 365 product & hit “Manage Account” the website that opens is https://login.live.com/login… as well as www.5dd.com (Chinese). Is this a virus that Avast should find?

Thanks,

Nothing wrong with the various bank links from inside the code, like: http://toolbar.netcraft.com/site_report?url=http://bank.ecitic.com

There is however a osCommerce hack known for an exploitable -lib/jquery.min.js, minified JQuery possible as such code is not too often reviewed and therefore there may be security risks involved.
