You're right, there's no way to universally disable macro support in Office 2004. The only solutions would be to live with the warnings or to upgrade to 2008 which doesn't support macros. Interestingly, in Office 2007 for Windows you can now disable macros altogether (in 2003 you could only disable untrusted macros).
That said, if your client is that worried, why not install antivirus?
As for why these docs don't appear to have macros, but say they do, I'm not sure. I just tested here: Created a new doc, added a macro, saved. When I opened it, it warned me about the macro. I then deleted the macro, saved again. Next time I opened it, no more warning. So if your Normal.dot is clean, I'm not sure why you're getting that result...
