Standardize word VBA usage within the team

I have a team of 10 persons who work on Word documents, they format per defined guidelines. We have created a macro that corrects the font, size and formatting.

How can I ensure that nob开发者_StackOverflowody can change/replace or delete this macro from their system? In case this happens I should get an alert.

Can something be done at the system or program level?

To ensure that no-one changes it, you can set a password on the macro. This page should get you there. But that won't help with notifying you.
