Annoying message regarding Adware.Webwise won't stop

Recently my Norton's Internet Security 2012 reports that I have a low level threat called Adware.Webwise, but it apparently won't remove it - since I tell it to "Fix" and it just keeps coming back.

After reading another post in this forum regarding this and following the instructions to Turn Off System Restore and do a complete scan, it is still there... I even got the latest version of Malwarebytes and did a Safe Mode scan with it, and Malwarebytes doesn't even report it as there.  Yet, everytime I start IE the Norton message appears again... This is very annoying... How can I either get Norton's to remove it or get Norton's to Ignore it?
