I assume you want to get rid of the security warning message.
Rather than lowering security, consider digitally signing the database. Look
in your Office folder, for a file called SelfCert.exe, which creates a
digital certificate. Then open up any code module in your database, select
Digital Signature from the Tools menu. Click Choose, then select the
certificate you created, and click OK.
The next time you open the database, you'll get the same warning, but this
time choose to accept the certificate, after which you will not see the
warning when opening that database.
