My opinion only: I still don't believe you know anything about Norton's capabilities and are just boasting about your IT background (why, I don't know.) I am very, very picky about the products I use...settling on any particular AV suite is an ongoing deliberate process where I've audited pretty much everything.
Now more to your points:
Even if Norton Enterprise solutions use a ton of resources, the consumer version does not. Also I don't buy that a small gain in effective threat reduction is worth trading away better resource usage, compatibility and ease of use...not when businesses are prepared to restore ghost images to eradicate malware infestations.
Here is a snapshot of the
two Norton processes in my Task Manager.
That's a resource hog, eh? If you want I can snapshot Resource Monitor too. In terms of disk activity, those processes usually sit at
zero unless there is a new file being scanned. <1% CPU, 12MB RAM, zero disk access...I'd like to see proof that Norton is anything other than a well-behaved background daemon.
Like I also said, the right solution for you isn't the right solution for someone else. That's why I named 5 different AV suites, each better at certain things.
Free: Comodo, BitDefender Free
Easy to use: NOD32, Norton
Fast: NOD32, Norton, Comodo
Resource usage: NOD32, Norton, Comodo
Advanced options: BitDefender, Kaspersky, Comodo
Compatibility: Norton
I use Norton because my ISP provides it for free and my previous selection (Comodo) broke. I suspect I might use it even if I did have to pay for it. I have considered going back to truly free options like Comodo, Panda, Sophos, etc., but honestly a year of Norton can be purchased on sale or after rebate for the cost of a fast food lunch. If/when Norton breaks, I will likely switch to something else. Inertia will keep me using it until then.
