This happened to me today for the first time;the attachment was a pdf
file. I was able to open the document when I right clicked on the
attachment and saved it; went to the saved document and it would
open. Even though it's an extra unwelcomed step, I was able to read
the document.
No, Norton AV is *not* a problem in this case.
Obviously you get bitten by the "IE8-WinMail-bug" which affects many
system (though not the majority) after having installed IE8.
So far no one knows what the reason might be.
And so far there is no fix - except uninstalling IE8:

Workaround:
The problems can be reduced to JPG and TXT files (all other files types
opening fine) with a workaround:
Right-click on the shortcut that you use to open Windows Mail.
Select Properties.
In the field labeled 'Start in' change the entered value to
%UserProfile%.
Click OK.
Restart Windows Mail and try opening attachments.
