try deleting the module itself

And for the other part of the question: yes, it's a Symantec issue - at worst
it should alert you that you're possibly sending something that has the
potential to be a problem to someone, but it should give you the ability to
actually exercise your gray cells and make a decision as to whether or not to
really send it.

You might ask if there's a setting in it that you can change over at this
site:

no registration required to ask or answer questions, and a lot of MSFT
Security MVPs hang out in that forum - along with lots of people sharp with
various security tools such as sNorton's plague products.

Kelvin,

First run your virus program to scan the Excel file you want to send. If
it checks out clean and virus free, you will be sending a good file.
Next, temporarily disable your Symantec [Norton, yes?] while you send
it. Right click on the Norton Internet Security icon [lower right task
bar] and find the 'Disable Virus Auto-Protect', highlight it and left
click it. A 'Protection Alert' window will open and let you select the
duration of 15 minutes, 1 hour, 5 hours, or until system restart. Choose
one of them and click 'OK', then go ahead with your e-mail. When you are
done, turn your virus program back on [repeat steps above] immediately
as soon as the e-mail has 'cleared' your ISP. Should work.

Regards,
Bert

General recommendation is to disable that "less than useful" feature of
Norton A-V. Also, if you have the Norton "Office Plug-in" turned on,
kill that problem child too.
