I downloaded something that in turn was a virus and screwed my computer up. I got everything else off but noticed Norton was downloaded. When I go to uninstall it, it says please wait... and never does anything. I have even tried the Removal Tool, and it still won't come off. My computer is running fine again, but now I can't even open Norton. It says it is already open. When I try to uninstall, it tells me, "A problem has occurred that needs your attention." It says it is still running, but it's not.
