|Uninstall that bloatware. Use Windows 7 built in utilities for maintenance and use Avast or Microsoft Security Essentials for antivirus. |
Norton tries to do everything, but does not do any of it that well. Windows 7 Disk Clean Up and Defrag work just fine and are fully integrated into the system for complete compatibility (Windows 95 did not defrag very well and other products were often needed to do a better job, but that was a long time ago).
Note that to completely remove Norton you will need the remover you can download from the Norton site.
You have to be a little bit crazy to keep you from going insane.
