mouse keeps scrolling up when i scroll down

I really have no clue as to why this could be happening after a fresh OS install. A friend with some computer knowledge suggested it could possibly be a virus, so I took advantage of the fact that I just bought a new SSD and installed it along with a freshly downloaded copy of Windows 10 through a USB stick, and did a fresh install wiping all my data. As soon as it boots back up, it goes back to scrolling to the bottom of pages like crazy.

However, it only fixes the issue until I put the laptop back into sleep mode or reboot it. Oddly enough, pressing the up directional key stops the weird behavior completely. The only way to get it to stop auto scrolling to the bottom of any window is to press the up button. Works otherwise just wont scroll on browser pages, Microsoft Word document. I tried with keyboard tester and all the keys are functioning as normal, and none are stuck either. Recently I started facing an issue where my Magic mouse would stop scrolling. On Vista SP1 and a IntelliMouse explorer 2.0, I'm seeing 'bounce back'. It flickers in such a way that it seems as if I had the down button pressed or stuck, but that is not the case. Mouse wheel scrolling problem ('bounce back' behavior). If I click on the grayed top part of the scrollbar to scroll it up by increments, it just flickers instead of actually going up. The same happens if I open a browser, Chrome in my case, the scrollbar goes straight to the bottom of any site I visit, as if I had the 'fn+home' buttons pressed down.

As soon as the OS finished booting up, I open the Documents folder, or any folder with enough files to have a scrollbar, and the scrollbar just goes straight to the bottom. The issue is that whenever I turn on my laptop (either from powered off or from sleep mode), as soon as it boots it just starts scrolling down by itself. This issue started out suddenly and completely out of nowhere, and it occurs even in safe mode.
