Is Norton 360 still being made or supported?

Hi.

I have a copy of Norton 360 I bought in June or July 2014. I have noticed a lot of stores are not selling this product anymore. They have Norton Security and Norton Security with back-up.

 

So what are the differences? Is Norton 360 still being made or supported? Do i have a time-limit to install Norton 360? Will it work for the full year? I need to re-install my OS's and want working malware protection that I paid for.

 

Thanks.
