Vista - Unexpected Interactive Services dialog detection

I'm getting an Interactive Services dialog detection message being displayed periodically on a system running Vista Home Premium.

In the notification, clicking Show program details expands the notification box to display

Message Title: Locate File
Program Path: C:\Windows\system32\comdlg32.dll
Received: current date and time

When I click Show me the message, a Locate File dialog box is displayed, with a pre-filled file type of Address matching data file (Address.cas)

I close the dialog box using the Close [x] button, click Return in the notification and return to my desktop.

I've just been closing the notification without displaying the message. I'm concerned that some sort of malware may have slipped past my McAfee security software, even though I've noticed no other ill effects so far.

Does anyone have any ideas about what may be causing this?

from my experience, some sort of installer that may not fully compatible to run in vista, the dialog box will appear , need permission from the user to run the software in a different environment. correct me if im wrong. thanks

Hi, carter_develops, and welcome to the forums.

Kianlie might have the right of it - have you installed any older applications that may have, on the surface, seemed to install correctly with Vista but in fact may be creating this error? Also, have you verified that you have the file located in your Windows\System32 directory?

Also, Hi, kianlie84, and welcome to the forums as well - good call on the possible reason there.
