The new Norton is a huge improvement on previous versions. Its quicker, slicker and does not hog resources. You may not want to try it "ever again" but PCA are right so recommened 360 as a top class security suite. And this is from someone that hated Norton a few years ago!
I have Norton on my laptop (it came with the machine) and KIS on my desktop (got it for free). I consider them to be equally as good. Norton prompts more frequently for scans and browser checks. I used to avoid Norton but the latest versions seem to be fine.
I have had harsh words to say about Norton in the past few years, and have heavily recommended firstly PC Cillin, then more recently Kaspersky, as my favoured suite for a paid-for AV.
I took part in the beta trial here. I did not expect much. I was badly wrong.
The product is transformed. It is excellent. Without a doubt, I prefer Norton 360 v3 over Kapersky, McAfee and Trend PC Cillin. It is immensely impressive in speed, very simple to use, hogs few resources and... well, is a pleasure to use.
