If you don't do a online renewal, wait till you see the pop up screen every 30 to 45 mins.

Symantec won't leave people alone, even uninstalling it won't get rig of the problem.
You got to go to their own website and find your own product from them and then get their own uninstaller to really get rig of software.
Even then....I don't know Symantec is one of those sneaky companies that would probably just leave yet another piece of info still in your computer just to monitor your actions. You think they won't do it? They sneaky enough to try!
