Macros suddenly in file... virus?

[t_habrock]

I have an Excel workbook that I created in 1998 - I have used it
continuously in the 7 years since then. Today for the first time ever
I received this pop-up window:

"The workbook you are opening contains macros.

Some Macros may contain viruses that could be harmful to your computer.

If you are sure this workbook is from a trusted source, click 'Enable
Macros'. If you are not sure and want to prevent any macros from
running, click 'Disable Macros'."

So I clicked "Disable Macros" and opened the file. Then I went to
Tools -> Macro -> Macros
to view all macros in this file and there are NONE! It is absolutely
empty. Anyone have any ideas on the following:

A) Could a macro be introduced into an Excel file without my doing it?
B) If there are no macros in the edit list then how exactly can I find
out why I am getting the macro warning and what can I do to make sure
that there are no viruses in there?
C) Finally, is there any way to scan for viruses in Mac (not
NORTON!!!!!)
I appreciate any help or insight anyone can provide.

Thanks guys!

The reason why you saw the warning for the first time may be that you just
enabled it. See Macro virus protection in the general pane of the
preferences.

Your workbook may contain macros even if they don't appear in Tools -> Macro
-> Macros. They may be in the workbook's or the worksheets' code windows.
Type Alt-F11 and double-click on the objects in the Projects window.
