Installed Norton, now told CS6 not genuine.

I have been using my computer for the last 7 years, bought the machine functionally to do a college course in music; I wasn't informed that the computer came preinstalled with Adobe CS6, unsure if master or web, but it has Photoshop, Audition, Flash, FireWorks, Encore, Prelude, InDesign, Illustrator, Premier Pro, Acrobat Reader... all function with no problem, no need to sign in, and I haven't updated, but rarely use most... but obviously over the passing of time, I use Photoshop, Dreamweaver, Audition and Premier Pro, and perhaps once InDesign, to do a CD cover for college work.

Anyway, due to what I perceived to be a malware issue, with my MacBook Pro memory suddenly shrinking inexplicably, I decide to install Norton 360 on my Mac to clear the problem, I did have Avast, but that expired, and I hadn't renewed, so used one of the group licences (4 licences between 4 machines, 1 licence used) my wife has to install the software on my machine.

Within a day of this Norton installation I start getting prompts and screen pops stating that my adobe software isn't genuine, I bought the machine from a business, who used the machine to do interactive websites, graphics, also on the machine is Microsoft Office. 
No I do not have serial numbers, to put it simply my wife works in insolvency, the machine was bought due to the sell of the insolvent company, the insolvent company may have had the serial number information, but I do not... and this was 7 years ago.

To put it mildly, I am feeling that my user rights are be usurped, by Norton analysing my computer and sending information to Adobe for them to install software on my machine that should not be there. It's an infringement, I didn't have an option to say, "by installing Norton we will analyse your machine to send information to companies that manufacture software you have installed" - since I use my computer for music - I have licences for complete suites of Arturia, Native Instruments, Eventide, Waves, Plug-in Alliance, and many others (and I maintain serial numbers of these); I find this sudden imposition of a pop-up stating that I have illegal software a sham to make me upgrade to cloud cuckooland versions of software I don't need, after 7 years or more of non-intervention, and now the sudden need for them to send me a link to uninstall the software, I feel my rights as a user are being usurped, with a bunch of hokey stating it's not genuine.

To add has said I have Microsoft Office installed, and have no such issue with them.
