Symptoms

When you click a hyperlink to go to an object or location outside of your PowerPoint presentation, you may receive the following warning message:

Opening file: path to filefilename.


Some files can contain viruses or otherwise be harmful to your computer. It is important to be certain that this file is from a trustworthy source.


Would you like to open this file?
This behavior occurs whether or not the Macro Virus Protection option is turned on. (To locate the Macro Virus Protection option, click Preferences on the Tools menu.)

Cause

The warning message described in the "Symptoms" section of this article is issued by Microsoft Office, not PowerPoint. This warning is referred to as the open programs warning, not the macro virus protection warning. It appears any time you click a hyperlink to a program or run a program. You also receive this warning when you click a hyperlink to certain types of document files. You cannot disable this warning. Similar behavior occurs in other Microsoft Office programs that allow you to use hyperlinks.

Workaround

To work around this behavior, you can use the Run Program option rather than the Hyperlink option in the Action Settings dialog box. This prevents the Open Programs warning from appearing in most cases.


NOTE: You can also turn off the Macro Virus Protection option in PowerPoint.

More Information

The macro virus warning is initiated by PowerPoint when you click a hyperlink to a file that may contain macros. When the macro virus warning is activated, the following message appears:

The presentation you are opening contains macros. Some macros may contain viruses that could harm your computer.
If you are sure that this presentation is from a trusted source, click Enable Macros. If you are not sure and want to prevent any macros from running, click Disable Macros. To disable this feature, click to clear the Always ask before opening documents with macros check box, and then click Enable. PowerPoint will not ask you again if macros are found in a file.


You can also disable macro virus protection by following these steps:

  1. On the Tools menu, click Preferences.
  2. Click the General tab.
  3. Click to clear the Macro Virus Protection check box.
  4. Click OK.
