White Rectangle

I had a white rectangle show up in the top left hand corner of my desktop. It was quite annoying. I tried changing the wallpaper, and killing a few programs in task manager. In the end I restarted windows explorer and that fixed it. Some people killed
other programs but those threads are locked. Hope it helped!

White Rectangle in top left corner - Windows 10





There is a small rectangular box at the top left corner of my screen. If I log in, I don't see the desktop items and only see this box in the corner. If I double click it though, my shortcuts and other items appear but the box stays in the background. It
is kind of annoying and I think It might be a virus. I recently deleted everything and reinstalled windows but this keeps on happening. How do I fix this?
