First thing is security

I prefer Norton because they are big and good leaders in problematic situation detection.
Plus I find Norton way cheaper than any other commercial security software here is why: Once you buy a norton antivirus software, you never have to buy an other version (until proven wrong)

So you are getting a warning that your antivirus is out of date? Then they refer to a norton page where you have to pay for membership renewal? Don't get caught in this publicity stunt. Norton has a page where you can go to manually update the virus definition.
