Hello, for some time now, a tiny square (1/1cm?) has been appearing in the middle of my screen. What's strange is that it doesn't disappear when I open a page, but if I hover my mouse over it, it appears to be underneath (the mouse pointer doesn't cover the square). I also can't right-click on it. It appeared for no reason, disappears when I restart the computer, and reappears at some point.
What should I do, and what is it?
Thanks in advance.

Hi,
press ctrl+alt+delete to go to Task Manager, normally all applications are visible, try to find the one that seems unusual and -> right click -> end task.
If you find its name, please post it here to help the next person with the issue.
Otherwise, it might be a background process, which requires a bit more investigation. If the window is active, it should be using some memory.
If that still doesn't provide any results, perform a virus scan.
