No, really,
Norton is shit, barely anyone uses it, the GUI alone is ugly and looks like scareware. If you are worried about any viruses, don't download trainers or cheats from suspicious or unknown sources, otherwise i can tell you that the trainer is made with Cheat Engine and it's probably not a virus, heuristic simply means "the world explodes tomorrow and we are all ******", in other words, it's worth nothing and makes more out of things than there really is. And if you already got adwares and malwares then it's probably time to ditch this piece of cake of an antivirus or whatever it tries to be. I'm using ESET and never have been infected, being cautious and use common sense is the key, no software includes it, it's human behaviour.
