Setting Macro Security

When you open a document, you might be prompted with a security alert. Documents can include additional programming codes called macros, which can contain viruses. You can protect your computer from viruses by running up-to-date antivirus software and setting your macro security level to high for maximum protection or medium for lesser protection. If macro security is set to medium, document users will be prompted to enable macros.
