When I go to websites, Hotmail etc that have white backgrounds & even Fbook. My computer screen rolls up & down uncontrollably & my mouse is inactive unless I press the middle button down on it & also use the left button.I get bounced out of Fbook & other pages. I don't think I have any viruses & I have downloaded multiple anti virus programs &done scans. I have been told it is a software problem. I can't system restore early enough. Help Please
