Is everything constantly scrolling down or to the side?

I have a very strange bug on my pc. With Netflix, all windows are constantly scrolling to the right. And windows where you can scroll down are scrolling down inexorably. No internet pages but new windows where you can choose something, for example. I can scroll up, but it goes straight back down.
I also restarted my PC and scanned it for viruses. It has been active for about 3 days now.

vi

Connect a different mouse. Then does the error persist?

Go with the mouse on the scroll bar and press the left button. Then does it stop?

After booting up, plug the mouse into a different usb port.

Yeah, I pressed the scroll key to the left, that was the problem.
