Can I delete N360 folder?

I am running Norton Security Suite, courtesy of Comcast.  I am preparing to take the plunge to W10.  I am trying to get everything "perfect" on my system before upgrading.  I notice I have a file folder entitled "N360_BACKUP" directly under C:  -- it contains huge subfolders, all dated in 2015.  I think I had mistakenly had Norton doing back ups on my C: drive cool.  I had turned that off last year.  Can I just delete this folder -- or how should I get rid of it?  BTW, I am now using another product to do weekly images of my HD -- and on an external drive  LOL.  TIA
