I am running Norton 360 V6 on a Dell Inpiron (Windows 7 64). I succesfully installed the newest version of 360, but now on every boot-up it takes a long time to initialize, and then I get a window from Norton Download Manager stating that "Norton 360 installed successfully, if you want to install on another device click here." If I open Norton 360, and run start-up manager, I find Norton Installer. Shouldn't the install upon completion remove the installer from the start-up menu? Should I just delete this from the start-up or should I try deleting the program and reinstalling?
