Windows 10: White Box Comes Up in Corner of Desktop

There is a white box that pops up in the bottom right corner of my screen that remains in the forefront and will not go away. It is blocking my access to that part of my screen. I have restarted my laptop several times and it will pop up again after a few minutes. I've check the task manager and haven't seen anything that would indicate it should be there. Does anyone know what this is?

White box appears in corner of desktop

Hi there,

A day ago a white box appeared in the corner of my desktop. It is always there no matter what I do. The box seems to automatically start when I turn on my pc. I cant remove it. It doesn't do anything when I select it. Please help me thanks.

 

Small white box on desktop (Windows 10)

Hi,

Let's try to isolate the issue. We need the following information:

• Is this happening only on the desktop?
• If you open an application/program does it have the same white box on the same spot?
• Regarding your scan, what do you mean everything comes back okay, does the report show no particular malware/virus or after the scan, the white box disappeared?

Looking forward to your response.
