across the top of the screen on my laptop Toshiba computer there is a long white strip. At the very left of the strip is a capital D in blue and next to it are a faded arrow pointing left, a faded arrow pointing right, and a faded capital C. Next to those are the words Search the Web. This started some time ago and I have done system restores but it is still there. Would anyone know what is causing this? Thank you. Anna Ruth
