I have a brand new Dell xps computer and installed Norton shortly after getting it. It came with windows 7 previously installed on it. I have been at school for a 2 weeks now and Norotn will not open. My computer will alert me in the bottom corner that it is trying to open and needs permission and once I give permission nothing opens. When I go into programs and try to open that way nothing happens or a tiny box will just appear in the middle of my screen. The tiny box is blank and will only let me minimize it or close it. Any help would be great. Thanks
