    Can't open or preview PDF files in outlook 2007

      I recently did all the recommended security updates for Office 2007. Since then I can't open PDF files anymore in Outlook. When I double click a PDF attachment I get a 'Attachment security warning that the file may contain a virus' The only option is then to save the file on the hard disc and open it from there, which works, just a bit complicated.

      Also the auto preview for PDF doesn't work anymore.
