I recently changed from a Wirledd net provider to Comcast/XFinity which as I understand includes Norton Security Suite as a part of their service. Both my systems already had Norton Internet Security installed so I am wondering does the Comcast version overwrite my version of NIS (for which I already have a paid subscription that automaticlaly updates)? I am asking this as my Norton Toolbar (2013.4.2.2) on the main machine has been disabled with a message that it currently is not compatible with Firefox 20. On the other system (which is running 22.0) it is working fine.
If so, how do I go about reinitiating the original install of NIS?
