Interactive Services dialog detection, Malware symptom?, Norton didn't detect it

OK friends... This came up and won't go away..Is it a symptom of Malware?

 

Windows Vista Home Premium SP2 on a Dell Inspiron laptop. I use Mozilla Firefox as my browser. I do a lot of personal stuff online, as many of us do, and when this started last night before an online banking session, I used another PC.

I can't get rid of it.

 

The Window:  Interactive Services dialog detection,

stating The program may need information or permission to complete a task

 

When I Show the program details, it says:

Message Title: Windows Internet Explorer

Program PAth: c:\Windows\system32\IEFRAME.dll

This problem happens because of partial incompatibility with Windows.

Please contact the program or device manufacturer(s) for more information.

 

I have changed nothing, It just started when I powered up and opened Firefox.

And if Windows Explorer, which I am NOT running, has a compatibility issue with Vista, wouldn't Microsoft fix it before releasing it? So why the message about something I'm not running

 

Have I uncovered a new Malware infection?

Norton scans have not detected anything.....

NOW, Microsoft has downloaded a new browser in the background, which I don't especially want (because of vulnerability issues that MS browsers have always had).

 

Having just dealt with rootkit on another machine, this persistent pop-up is scary.

I have looked online, and

some people disable these messages,

others say you shouldn't  ever do that

and yet others that say it's a sign of Malware>.....No consensus.
