I know this question as been asked many times in the past and I have
searched for a fix for my situation but haven't found one that works.
Here's what's happening:

I have a workbook that does have lots of macros and is an XLSM file.
One of the macros copies one of the worksheets (doesn't have any
macros) to a new workbook. It then updates the data in the new
workbook and finally saves it using an "XLS" prefix. When I open the
new workbook I get the macro warning. I tried the following code
before the save to get rid of any macros in the new workbook and while
it does find 2 VBE component it doesn't get rid of the macro warning.

With ActiveWorkbook.VBProject
For i = .VBComponents.Count To 1 Step -1
.VBComponents(i).CodeModule.DeleteLines
1, .VBComponents(i).CodeModule.CountOfLines
Next i

For i = .VBComponents.Count To 1 Step -1
.VBComponents.Remove .VBComponents(i)
Next i
End With

Is there anything else I can do to get rid of the macro warning from
the new workbook? I know I could create a new workbook instead of
coping the sheet but I'd like to preserve all of the formatting,
headers and trailers without having to add setting them in the macro.

Thanks for your help.
