Note Because macros can contain viruses, be careful about running them. Among the precautions you can take, be sure to run up-to-date antivirus software on your computer, use digital signatures, and maintain a list of trusted sources of macros.
To perform these procedures, you must have Microsoft Internet Explorer version 4.0 or later installed on your computer.
Do one of the following:
Add a macro developer to the list of trusted sources
Remove a macro developer from the list of trusted sources
On the Tools menu, click Options, click the Security tab, and then click Macro Security. Click the Trusted Publishers tab, click the publisher source you want to remove, and then click Remove.
