I am using windows live mail -windows 7- and have 2 messages with attachments that I have accessed numerous times.   This morning when I

  tried to open I get a pink file header stating_ Prohibited file type-  this file contains a attachment whose file type is considered dangerous. This file has been deactivated.        I cannot open the file . I know there were Microsoft updates done this morning and when I tried to restore to a earlier date the

computer would not restart  and after some time some auto type fix was done but I still have the pink file header with a attachment I cannot open.

 Has anyone else seen this ?
