Active content types in your files (2024)

Check files by using Trust Center

In Trust Center, you can configure checks of content in files for computer viruses or other security hazards that can be delivered to your computer by active content. These checks prevent active content from running automatically, which helps to protect your computer and network by preventing unexpected or malicious content from running.

To learn more about Trust Center, see View my options and settings in the Trust Center.
