Anyone know what Norton is like these days?

My Dad's girlfriend's dad bought her a laptop last month from PC World. I think the spec was a little outdated but it would be fine for what they want (accessing the internet downstairs), and they got it at a good price.

But of course he was tricked into buying Norton, so my Dad has decided they will use that on this laptop since they have a years worth of it.

So, I was just wondering if anyone here had used it recently, and if so, is it any good, or it is just a pain in the backside*?

*Most security software it like that in my opinion, but some is definitely worse than others.
