Have you even tried the current Norton Internet Security on the PC or Mac? It works great on both. Do a little research before making ridiculous comments. It doesn't help anyone.
On the Mac, it's completely unnecessary, so I am not even going to rise to that. On the PC, Norton is widely agreed to be buggy, a resource hog and in some cases as difficult to remove from your system as a virus itself - not to mention needlessly expensive. MacAfee is just a joke.
Norton corporate/enterprise is actually quite a lot better - I have it on my office PC (I have no choice) and it's fairly unobtrusive. But the home version is a pain, especially if you're a gamer or a tinkerer. There are far better solutions.
As for your snide comment, it got a negative rep from me (I don't do anonymous). I think my comment WAS helpful, and I generally try to add value to this forum in any way I can. 30+ years of experience with computers helps in that regard - the reason I didn't go into a bunch of better PC solutions, is because this is not a PC forum - however I'd recommend these ahead of either Norton or MacAfee:
- Windows Defender (it's free, and no one has more interest in keeping your system safe than Microsoft)
- Kaspersky (low price, small footprint. This is the one you want on your VM or low powered machine)
- Bit Defender (never bothers you, easy to install or remove, attacks malware, very affordable)
- AVG (free version, actually pretty good although slightly clunky interface)
Cheers.
