Norton 360 restores files that can't be read by my computer

I recently restored some document and pictures using Norton 360.  When I try to access the Word documents, it brings up a message box saying I need to select the encoding that makes the document readable.  Except none of them work.  The text itself is there for some of the languages, but the formatting and layout are garbage, and there is a bunch of nonsense characters strewn about.

 

Also, I tried opening them with the pre-installed version of Microsoft Works, and it said the filetype was not supported or the files were corrupt.

 

I then tried to open some of the pictures that I restored along with the documents to see if the problem was a little more widespread, and nothing (not Paint, Picture Gallery, or Office Picture Manager) would open them.  The pictures are .jpeg and the documents are .docx, so I can't figure out why they wouldn't open.

 

I ran all updates for Windows and Norton.  I tried to re-restore the files, all to no avail.  Has anyone seen anything liek this?  I suspect that my backups are corrupt and that I am out of luck, but I wanted to pick someone else's brain before I gave up.

 

Thanks all,
