I have a laptop with a touchpad and a usb mouse. Every now and then, the computer decides to scroll down the list without me even touching the mouse.
I thought maybe there is some problem with the touchpad, as this happens even when the mouse is not connected. I went to the device manager and uninstalled the driver
for my touchpad, but even then, same thing still happens just like before even when I have unplugged the usb mouse.
It might be worth mentioning that often, the way to stop this auto-scrolling is to press the Esc button or the up arrow key. usually but not always that stops it from happening.
Also, I did a full system scan with the AVG Antivirus and no issues were found. I should say I also have SuperAntiSpyware and MalwareBytes running so I don't think it's a malware issue.
