Windows 7: Why does "core" empty window appear on my desktop from time to time?

Why does "core" empty window appear on my desktop from time to time?

From time to time, unpredictably, I get a small empty window appearing on my desktop with the word "core" in the top left corner. You can see the window in the attached files.

Checking in task manager, "coresync" seems to be using 100% of memory

I have to shut the computer down to get rid of the process. I believe it may have something to do with Adobe's Creative Cloud desktop app but I don't what it is. My CC version is 2.0.0.74 (the latest). I am using CC's File Sync.

I am running Windows 7 Pro 64bit OS on my machine and the system appears stable. I am using Photoshop CC 2014 64bit and Dreamweaver CS3. My machine specs are:
CPU 3770K ; an Asus P8Z77-V Deluxe motherboard; 32Gb Crucial DDR memory; a Crucial 256Gb SSD for the OS and programs; x2 Samsung 512Gb 840 Pro SSDs for data; an Asus GTX660 graphics card.

The problem just started out of the blue. I am not aware of changing anything. I have researched this in Adobe's forums and Googling have not been able to find an answer.

Can anyone help me with this please? What does it mean if an empty window appears?

Thanks

(NB If one is running Kaspersky security it may rant about ADW - just ignore it or disable Kaspersky while the ADW is being used)

And while running in safe-mode, look in these places. This will tell you what program puts up that CORE window, and will tell you how it gets executed in the first place.

In the registry, look in these two places:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

In the file system, look in these two places:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup
C:\Users\<YOUR-USER-NAME>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

Just wondering margrave what should be in there? mine comes up with a string odf variables for APPDATA and to be honest am not sure of what I see in any of them.

A Google come up with refs to malwares which I think with the sfc and chkdsk I would like to see first. Ideas??

Just to report that on a hunch, I removed "Nvidia Experience" from my pc a few days ago and have not seen the empty "core" window since. Too early to tell if this is just a coincidence but it is encouraging.

That's a start at least let us know how it goes.

spoke too soon...

I spoke too soon. The "core" empty window came back with this morning's boot. It's definitely related to Adobe CC because for a moment after I killed the application in Task Manager I saw words like "the creative service has stopped" or something like that. So I'm back in the market for help...thanks for any other ideas.

David just to humour me can you run those scans I posted earlier as I did see some refs to malware and well Adobe isn't known for its infallibility for want of a better term.

Plus it might just be the system a little out of whack.

Thanks ICI2LOL. I ran file checker and disk checker. The file checker found some problems - screenshots attached. I cannot open the CBS text file ("access denied"). So I don't know where I go with this.

I also ran malwarebytes - no problems found.

What next?

I copied the CBS log file to the Desktop and now can read the file. It is massive and incomprehensible to me. I can't see any references to corrupted files that could not be fixed - but I lost the will to live after reading down through the first 3ft of the log.
