Since you must have virus protection nowadays, this is better than nothing.
But, as was pointed out earlier, Norton AV expires after 1 year, and uninstalling/reinstalling resets counter.
At the very least you should clean out your system a least once a year anyway, so Norton's expiration should be a non-issue.
In the past couple months, I have seen a lot of PC's come in for repair's that were infected with viruses.
Many of these were running Mcafee.
Norton found and removed viruses in all infected systems, every time.
With the deals here in this forum, have seen full version of Norton for free, or many cases where it was under $10.
All virus protection programs work GREAT..........................................................until you get infected..............
