If I have Norton 360 do I still need internet security or it is just OK to have the 360 only?

In my point of view, Norton 360 premier edition is the best one because the Norton 360 premier has backup utility where it backups our data and restores the data to the original destination.

Norton 360 which has limited features where backup and pc tune up is not available where Norton 360 premier edition has.

I have used Norton 360 but it seems to be not fit to my computer where my system is low in configuration and my system will become very slow when I installed it and so I removed it, Installed Avast free edition that was better for me.

Not only 360, any security software that is provided by Symantec was awesome and in that Norton 360 premier edition provides 25 GB of cloud storage that is also a secure. Just don't install the Norton Internet Security which has the better features where one can afford to buy the security software.

Once before buying or installing the antivirus once check the features of the that particular security programmes and so you will come to know whether need to install any new softwares or ...etc
