NIS icon taskbar not responding

There is a icon from NIS 2011 in the taskbar of windows 7 which has a green v in it so it looks like it is working but i am doubting. So right click does not work on the icon, as the matter a fact, the icon is not responding to everything..

I cannot configure NIS2011 anymore.
How to solve this, uninstall and reinstall? I have tried that but maybe then keeping the settings not.
Is this happened by ohters?

Do you have any other antivirus or firewall products installed? If yes, you need to remove them.

 

How did you uninstall and Reinstall the Norton product last time? Did you use Norton Removal Tool? If not, please try that using the Norton removal Tool. You can find the instructions in the following Support Article:

 

Norton Removal Tool

 

After you run the Norton Removal Tool and restart the computer, you get a Web page with the steps to download your Norton product. Download it and install it.
