F4E: Thank you for your answer. Yeah It's exactly that driver. I thought most likely that it was a Norton File but I was not sure. My computer is working fine so I don't think that I am infected. I just wanted to try the Power Eraser to be sure. But I guess the normal full scan should be enough then? But the Eraser can not remove critical programs if I chose not to? Or can it remove it by itself/Automatically due the scanning?
Disted2: Thanks for your advices. I already have Malwarebytes Pro. Are you sure that Malwarebytes cant run in real time at the same time as Norton 360? I remember that I saw something on their site and they wrote that it in most cases should be OK to run Malwarebytes and Norton in real time at the same time, because they work differently?
