Thank you for the responses.
Of course, I know I am free to make my own choices regarding my own computer and with what purposes I attempt to accomplish with it, but if I am not able to 'defend' what I do, that means I cannot explain it and don't know what I am doing, so I always have a defense ready. If not, then I seek answers from others.
I know the basics: whenever ANY program is running, Norton or otherwise, it will reduce computing cycles and cut into memory and other resources. The more 'clothes' you put in the 'closet', naturally, the closet will lose space.
I turn on Windows update periodically to update Windows defender and install important security updates. Then when they are installed, I turn off Windows update. This is simply because if I leave WU running, it is tapping into my connection when I am working on other things, which then causes very untimely delays. Norton did the same thing. PC Health Check did the same thing. Java update did the same thing, as did Media Player Network Sharing, the latter of which completely ignored my off command to the point where I had to rename the .exe file to a .bak file so it would not run at all.
Bottom line: I don't want any program, process or thread running without my explicit consent, and furthermore, any attempts to override my permissions (e.g., won't let me rename the file), means I will either delete the program or have it removed. I want full control over my system, and I want to know the purpose of each and every process running, because I don't like my cycles being eaten up in the background.
There are two things that occur: the processes and programs the operating system programmers (and Norton programmers) think I should have running, and those that I want running. I do trust them up to a point, but when I check my startup manager says the origin of any program is unknown I deactivate or delete it. It's that simple.
The only time I have ever had to do a clean reinstall of the system is when I downloaded "too many updates," more specifically, HP Updates. Norton always did it's updating rather discreetly. Scheduled maintenance always cut into whatever I was doing at eactly the wrong time.
Jewel quest ratings, by the way, are always fluctuating, so you could be #1 one minute, and #5 the next. If I don't play, it's irrelevant anyway.
Something was causing a delay between my mouse movements and my keystrokes, and I suspect it was Norton. This doesn't mean that I won't reinstall it at some future time, but for now, I really like the speed and efficiency at which my system is running now. Anything new that I add will only slow it down. That's where I came up with the idea that Norton is being "overly aggressive." It doesn't mean that I am right, it only means that's what my perception of the matter was.
Thank you for sharing. Oh, and by the way. If I justify something, it is by my choice alone.
