The programs included with Office that support the use of
Visual Basic for Applications macros also include macro virus protection.
If this feature is selected, you receive a warning message whenever you
open a file (such as a workbook or a document) that contains macros.
In some cases, you may receive a macro virus warning message twice when you open a file by using any of the following methods:
- You open the file in the program that created it.
- You insert the file into a document in another program.
- You insert the file into a binder by clicking Add
From File on the Section menu.
This behavior occurs as a result of how the file is opened or
inserted by the program you are currently using.
