Why do these keep reappearing when they're not part of my product?

Indeed, I've read all the posts across the forums. This has permeated into all the Norton A/V products, shouldn't be there as it presently is whether or not the features are present. The user has ownership of their machines, NOT a software company. Windows doesn't need nor require third party tools to manage things on its own. This is nothing more than bloatware marketing. And no, some of these features are NOT just found in Norton Utilities, tulH.exe and nuPerfScan.exe create the history entries so there is a master plan at hand. I DO NOT want a system I spent 5K to build become unusable because of BS running in the background I neither asked for nor installed. Makes prudent sense doesn't it?
