Small white square on screen

I have recently noticed a small white square on the bottom right of my laptop screen. I have absolutely no idea what that is or how to take it off. Here is a print screen.





This little white square is not on the top of everything on the screen. If, say, I click on the notifications button, we do not see the square





Any idea of what that is? Or how to get rid of it?

If it is relevant, on the tray I have:

• CCleaner
  
• Acer Care Center
  
• GeForce 920M
  
• Avast
  
• NVidia GeForce Experience
  
• Avast SecureLine
  
• Drive File Stream
  

My computer is an Acer Aspire E15 with Windows 10, 64 bits.
