Franko, whilst this might not be your issue directly, and this is just advice that you can take or leave , completely uninstall Advanced System Care and uninstall Norton by using the Norton Removal Tool available off their website and install Kaspersky Internet Security or BitDefender Internet Security, even the new Microsoft Security Essentials (completely free from MS) is rating well nowadays.
Many will argue that their AV is the best, but many people will tell you what an impact Norton can have on your system and Advanced System Care in my opinion and experience can do more harm than good on a system.
