Curser Randomely Jumps to Top Right Corner and Clicks

So recently this really annoying problem has been occurring where when I'm doing something in Microsoft Edge, the curser randomly jumps to the top right corner of my screen and clicks, closing my tabs. This problem does occur in Google Chrome too. I don't
touch my touchpad, so that's not the problem. I have not recently messed with any settings for my laptop. Could it be a virus?

 

Curser keeps jumping to top right of screen and minimizing anything I am on

Curser while screen is extended.

This computer has Windows 10 and two monitors. The screens are expanded. How can I adjust the appears of the cursor? To move the curser from the screen on my left to the screen on my right. I must scroll the curser all the way to left. Then is comes
appears on the right side of the screen on the right.

I am at work and can't just swap the monitors. Internal tech support do not see this as a problem; its just part of their configuration and it affects only half the computers. The clients see this, think its weird, and question other things the computer
is doing.
