Norton, back in the day was good. Since ohh 2002 or somewhere around there they lost their way, the software got bigger and it got hit by EA syndrome - Producing a new version every year just for the sake of it, not because their are new features.
As a result of that they have to do new things and integrate with everything just to justify the new version. To force people to get the new version they also don't release virus updates for the old editions.
That is why I don't like Norton. However AT you should take less caffine (of whatever you take
) because no virus firm is going to make viruses. That is just ridiculous.
