Warn about installed templates and add-ins

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.

Depending on your macro security setting, when you open a macro, you will receive a warning and the macro may be disabled for installed templates and add-ins (including wizards).

  1. On the Tools menu, click Options, and then click the Security tab.

  2. Under Macro Security, click Macro Security.
  3. Click the Trusted Publishers tab.
  4. Clear the Trust all installed add-ins and templates check box.

Note  All templates, add-ins, and macros shipped with Microsoft Office 2003 are digitally signed by Microsoft. Once you add Microsoft to your list of trusted sources for one of these installed files all subsequent interaction with these files will not generate messages.
