i use comcast xfinity cable and they tell me i can get norton antivirus for free as long as i have comcast. my question is this, what norton system does the comcast user get, and just how good is it for the comcast users? is it worth getting? i now use avast free and ccleaner free and malwarebytes free as the win10 forum guys told me a few years ago that was better. but i'm thinking these are starting to slow down my system and maybe getting just one program would be better. so as long as comcast provides security for free i might as well sue it. but is the system that comcast gives us for free really worth getting. thanks
