Can I use Norton Removal Tool to uninstall Norton Utilities 15? I cannot use Uninstall function

Hi,

 

I'm getting a bit desperate here.  Ever since I've installed a new version of Internet Security a week ago along with Norton Utilities 15, our web pages take up to 2-3 minutes to load.  Might be a complete coincidence but somehow I don't think so.  Does anyone know if 2012 version of Internet Security was significantly changed, would it have something to do with real time protection function?  Anyway, I've decided to uninstall Norton Utilities 15 first the next day to see if it makes any difference, and in desperation I also did System Restore soon after which was a bad move because all it did was to bring back a copy of Norton Utilities without some important files.  Now, when I go to Control Panel and click on Uninstall the copy of it, it gives me a message that NU15\unins000.msg file is missing....  When I want to use my Installation Disk in order to try to re-install it, it tells me to uninstall the version that I have on my computer first using Uninstall function.  Arrrgggh!!  Where can I get missing file/files or can I use Norton Removal Tool for this?  Thanks for any suggestions....
