When you go on to open a Microsoft Office file, you may have noticed that it is opened in Protected View.  When files are opened in Protected View, you can read them, with minimal risks to your Windows computer. If Microsoft Office detects a problem with the file you will see the following message:

You may receive such messages if the files contain macros, data connections, ActiveX controls or even malware – and File Validation / Trust Center is detecting a problem with the file. It could be a malicious file or for a damaged file. You may receive even receive such messages, when you go on to open an embedded object, perform a mail merge or open a file from a viewer.

If you continue to receive such messages, you can change the default Trust Center settings to a less-safe macro security setting or even disable Protected View. But this is not recommended.

A better option would to move such files to a Trusted Location. You can add trusted locations, in any Microsoft Office document like Access, Excel, Visio, Word and PowerPoint

If you do this, Office files will not checked by Trust Center or opened in Protected View. But remember – you have to be very sure that the new location is completely secure.
