I used Norton software from 2000 to 2012. I had some problems with Norton over the years. Windows 98se, 2000, and XP.
I've used McAfee software from 2012 to now. I have had ZERO problems with McAfee, software has worked perfectly. Windows 7, 10.
I don't care what anyone buys or doesn't buy; just answering OP questions.
Online Code (downloads from Amazon) - Amazon software download center may end download a year or two after purchase. I always buy the Key Code (downloads from McAfee) version on sale and download/install sometimes a year later.
