Cookies from Norton/Symantec itself? That would be a little bit strange, that it finds its own cookies worth a message.
Or other cookies that it finds during a scan?
Cookies, of course, are user- and browser-dependent. It's not a Windows thing, it's a user/browser thing. So deleting a cookie depends on the browser.

Does anyone has any cognizance of tracking cookies found during Norton Scan?
How can I remove it manually?
