I personally gave up Norton years ago, when it got bigger than its own ego and stopped having customer service, and took zero responsibility for their product and actions of it.
I also used to get a lot of false positives with Norton, which are better than a false negative, but none the less, annoying at best.
But to be fair, you should contact them, either through their email, or by phone ( if they don't charge for phone calls). Have your log information handy, so they can reference any #'s or whatever they need to.
There are many different configurations with both hardware and software. How yours is configured is up to you and you alone. It would be completely unfair to guess at what any of those warnings mean without knowing more details than we have. And what we do here is warn about scams... we aren't a group of computer guru's ( Geeks)....
