Windows Security Dialog Box Prompt

[theCharcoalsky]

I've been having this strange issue for the past few months where the windows security dialog pops up for literally no reason.  Whats even better is that I have no idea what credentials it wants.  If I put in my username and password for the computer it goes away, but it also goes away if I just hit "OK."  It has no "Domain" attached to it or something that would give it context.  I've attached a few photos in case it would give anyone some help.  The first picture is the dialog box itself. The second is the task manager process of it, which is just a normal Windows Explorer app.  The final photo is following the file location right into windows.  I literally have no idea why I keep getting prompted for nothing.

It could be, though I scan with MBAM every day and that's up to date.
