I was going through the system preferences on my mac and when clicked on Mail, Contacts, & Calendars, I saw that some foreign language mail clients showed up that I could set up. They look either Chinese, Korean, Japanese, or Vietnamese. Here are the clients: mail.163.com www.126.com mail.qq.com weibo.com youku tudou.com Before, the only options I had as mail clients were: iCloud Microsoft Exchange Gmail Yahoo! AOL Twitter Vimeo Flikr Where did those extra mail clients come from? Is this a virus?
