Over the last month, the home page of my website hosted on Media Temple's grid server and has been appearing in google listings as an https website.  I have never requested or needed the extra security of ssl and as such have not purchased a secure certificate.  I have submitted a xml google site map for the site and added a .htaccess redirect to the correct http file.  I am at a loss as to why this is happening.Any advice would be much appreciated.
Google indexes my site as https as opposed to the correct http
