Hello group
In one PC of mine that have the Office 2003 version the excel had this
annoying problem of excel macro notification

The workbook contains a type of Macro( vesion 4 .0) that cannott be
disabled. There might be viruses in these Macros. If you are sure this
macro is from trusted source click to open the workbook


Security Warning
Macros contains viruses.It is usually safe to disable macros,but if
the macros are legitimate, you might lose some functionality.
then below it are boxes that says
Disable Macro , Enable Macros
