I bought this to replace (the now outdated) Norton 360 that I had been using as the cost of replacement was less than a third of the cost of renewing when I took into account the fact that I could replace rather than update Norton Mobile on my phone and tablet as well. Why Norton do this I don't know. I am a long term customer and contacted them but they assures me the renewal cost was right while agreeing that replacement was much cheaper. Anyway, it does everything 360 did with the addition of Norton Utilities. The only slight catch is that I think my computer is marginally slower with this version but not unbearably so.
