Norton anti virus is not offered for free of charge, but it only provides for 15 days free trails only. License is required, it means that you need to purchase the license in order to get product key and use it.

There are many anti-virus software provide for free of charge like AVG anti virus, Bitdefender, Avira Classic, Avast and more. You can find more here:

It is a good resource, I would recommend you to read.

Yahoo antivirus?free spyware remover

Get AVG antivirus in combination with Spybot-Search%26Destroy. Update both and run a scan on your computer. Both are freewares and are better than norton. AVG scans for viruses and Spybot takes care of adwares, spywares and trojans and removes them using its secure shredder. These freewares are lite on your system memory and does not slow down your computer. You will like this combination than Norton. I have not been infected for over three years now with this combination.
if you need the product key it aint free dump norton---avg free edition is good and FREE
