I am getting the above error. It seems that "Sonar" stops working. I have done the "Live Update" until no more update required and rebooted. When the machine starts all is OK after a while Sonar seems to switch it's self off

Hello caneman,

It seems you have performed all of the initial steps in the KB which addresses this issue. From your past posts, it appears you are using NIS 2011.

The next step would be to uninstall and then reinstall the product.  I would suggest using the procedure below for a complete uninstall:

Please follow all the steps even if they seem redundant.

• Download and Save the Norton Removal Tool to your desktop.
• Download and Save the NIS 2011 Installer to your desktop.
• For temporary protection, turn on your Windows Firewall.
• Back up your Identity Safe Data to a convenient location. Have your product key handy.
• Uninstall your current Norton Version via Add-Remove Programs or Programs and Features.
• If prompted, do not select the option to save your settings.  Select "Please remove all user data...." (see image here)
• Restart your computer when prompted.
• After the restart, run the Norton Removal Tool.
• Restart your computer when prompted.
• Right click on the NIS 2011 Installer and select “Run As Administrator” (XP users just double click).
• If prompted, enter your product key and set up your Norton account.
• Check that Norton has turned OFF the Windows Firewall.
• Run Live Update a few times until no more definitions are available.

For your convenience, I have attached printable instructions.

Thank you for your quick reply and detailed instructions. Is there anyway I can download NIS 2011 without the NIS 2011 Installer? Manual download?

The link I provided is for the direct product download.  No download manager is included.

Thanks. Will try a new install.
