You cannot disable warnings, but if you install the add-in properly
(ToolsAddins...) and not just load it, you won't get the warnings.

After you have deleted the file, go back into ToolsAdd-ins and select that
addin. It should say it doesn't exist and offer you the opportunity to
delete it.

I have Excel 2000. I use Excel VBA to write program codes and I save the
file
as xla add-in. Excel gives the message that the addin file contains
macros,
macros may contain viruses .....
Can I disable the warning for only this one add-in ?
Also, how could I make the add-in de-listed from the list in [Tools],
[Add-in], [Add-in available:] window ? If I simply delete the xla file,
the
add-in is still listed, and warnings on the missing file appears when I
launch Excel.
Thank you.
