What are you trying to do when you get this message - view a page, post a comment, view an attachment, post a photo?
What type of device are you on - computer, phone, tablet?
On a computer, just clicking on pics that people post which show up as attachments - I can see the thumbnails but when clicking on them, a new tab opens with that message.

I've gotten an error message while clicking on attachments, but only when I was browsing the site without being logged on. But it wasn't the particular message that you are receiving. I will see if Slinky can shed some light on this.
Try a different Web browser if you are using a computer which will narrow it down to that or your account. If you Google it you will find that it is a common message that isn't specific to any one program or app and sounds like it has something to do with Microsoft admin privileges or perhaps some malware on your device.
