Hi Pat,
This is becuase of your security settings, you can easily change the level
of securty to not inform you.
When you open a file in Access 2003, you might see a warning that states
that the file may be unsafe if it contains code that was intended to harm
your computer.
You may see the following warning when opening a file, if the macro
security level in Access is set to High:
Access cannot open the file due to security restrictions. Security settings
restrict access to the file because it is not digitally signed.
You may also see other similar warnings about your file not being safe.
These messages are a result of new security features that are part of
Access 2003. For more information about these security features and how to
avoid these warnings from appearing each time you open a file, see
Frequently asked questions about Access security warnings.

Macro security levels
The following information summarizes how macro (macro: An action or a set
of actions you can use to automate tasks. Macros are recorded in the Visual
Basic for Applications programming language.) virus protection works under
each setting on the Security Level tab in the Security dialog box (Tools
menu, Macro submenu) under different conditions. Under all settings, if
antivirus software that works with Microsoft Office 2003 is installed and
the file contains macros, the file is scanned for known viruses (virus: A
computer program or macro that "infects" computer files by inserting copies
of itself into those files. When the infected file is loaded into memory,
the virus can infect other files. Viruses often have harmful side effects.)
before it is opened.
Security Because macros can contain viruses, be careful about running
them. Take the following precautions: run up-to-date antivirus software on
your computer; set your macro security level to high; clear the Trust all
installed add-ins and templates check box; use digital signatures; maintain
a list of trusted publishers.
Very High
This setting is not available in the Security dialog box in Microsoft
Office Access 2003. It is possible, however, to use system policies to set
the security level in Access to Very High. When the security level is set
to Very High, Access cannot open any Access database (Microsoft Access
database: A collection of data and objects (such as tables, queries, or
forms) that is related to a particular topic or purpose. The Microsoft Jet
database engine manages the data.) or Access project (Microsoft Access
project: An Access file that connects to a Microsoft SQL Server database
and is used to create client/server applications. A project file doesn't
contain any data or data-definition-based objects such as tables and
views.) files.
High
Unsigned macros
The file can be opened only if the user chooses to trust the author and
certification authority.
Signed macros
The source of the macro and the status of the signature (digital signature:
An electronic, encryption-based, secure stamp of authentication on a macro
or document. This signature confirms that the macro or document originated
from the signer and has not been altered.) determine how signed macros are
handled.
A trusted source. Signature is valid.
Macros are automatically enabled, and the file is opened.
An unknown author. Signature is valid.
A dialog box is displayed with information about the certificate (digital
certificate: Attachment for a file, macro project, or e-mail message that
vouches for authenticity, provides secure encryption, or supplies a
verifiable signature. To digitally sign macro projects, you must install a
digital certification.). The file can be opened only if the user chooses to
trust the author and certification authority. A network administrator can
lock the list of trusted sources and prevent the user from adding the
developer to the list and opening the file.
Any author. Signature is invalid.
The signature might not be valid due to several reasons. For more
information on files and VBA projects with invalid signatures, see the Help
topic Troubleshoot macro security level and warnings. User is warned that
signature is invalid, and the file is not opened.
Any author. Signature validation is not possible because public key is
missing or incompatible encryption methods were used.
User is warned that signature validation is not possible, and the file is
not opened.
Any author. The signature was made after the certificate had expired or had
been revoked.
User is warned that the signature has expired or been revoked, and the file
is not opened.
Medium
Unsigned macros
User is prompted to open the database or cancel the operation. If the user
chooses to cancel the operation, the database is not opened.
Signed macros
The source of the macro and the status of the signature (digital signature:
An electronic, encryption-based, secure stamp of authentication on a macro
or document. This signature confirms that the macro or document originated
from the signer and has not been altered.) determine how signed macros are
handled.
A trusted source. Signature is valid.
Macros are automatically enabled, and the file is opened.
An unknown author. Signature is valid.
A dialog box is displayed with information about the certificate. The user
is prompted to open the file or cancel the operation. The user can choose
to trust the developer and certification authority. If the user chooses to
cancel the operation, then the file is not opened.
Any author. Signature is invalid.
The signature might not be valid due to several reasons. For more
information on files and VBA projects with invalid signatures, see the Help
topic Troubleshoot macro security level and warnings.
Any author. Signature validation is not possible because public key is
missing or incompatible encryption methods were used.
User is warned that signature validation is not possible. User is prompted
to open the file or cancel the operation. If the user chooses to cancel the
operation, then the file is not opened.
Any author. The signature was made after the certificate had expired or had
been revoked, and then the file is not opened.
User is warned that the signature has expired or been revoked. User is
prompted to open the file or cancel the operation. If the user chooses to
cancel the operation, then the file is not opened.
Low
When security it set to low, all macros are treated equally, regardless of
origin or certificate status. With low security, you receive no prompt or
signature validation, and macros are automatically enabled. Use this
setting only if you are certain that all macros in your files are from
trusted sources.
