Have a Dell Latitude E7250. Whether using my mouse or touchpad, the scroll shoots to the bottom and while I try to move it up it shoots down. This occurs on Chrome, Firefox, IE/Edge, and with files in my folde, and at times the window looks like it's shaking. Also, sometimes trying to search, random urls appear in search box. Ran scans but no viruses nor malware was detected, updated driver cleared Chrome browser and cache (chrome is the predominantly used browser. Looking for help and what to do next.
