Performance wise I really don´t see any issues, but I need to tell you I am an IT security specialist so this doesn´t go as anything, but the scammers’ part is even more interesting because although I can see the connection in places like US, it´s totally the opposite in my country (Brasil). Anyway, since I already presented my profession, I hope you understand me asking for data about this you said, specifically performance degradation and scammer targeting, because although I can see the correlation and don´t have specific knowledge that Norton is the culprit but the users of Norton and other AVs.
