Ok so I am in need some answers. When I am browsing on my comp, using Mozilla, my window will randomly close, the start menu will pop up, I will not have full control of my mouse and random programs will be selected, they don't seem to ever be the same ones, and the last time it went to my printer selection screen. I am really confused as to why this is happening and if this could be a virus or something worse. Please anything would be appreciated and helpful.
