You have either a stored entry in tools/options/applications that zip is file/x-msdownload or the windows registry reports tis content-type forthe extension.

This happens because you downloaded a .zip file and many servers sends the file/x-msdownload content-type for downloads. The content-type is stored if you select that the download decision should be remembered.
