Just a week before Christmas I received a message that an update for Norton Internet Security 2006 needed to be installed, so I followed the prompt and started the process. I received an error message the first time that the update couldnt be completed and that I must restart my laptop and try to install the update again. Upon completion of the restart and a second try at the update, the entire application was deleted. Since then I cannot seem to download anything that resembles a virus scan. Have I picked up a virus or what

I have Norton 360 Version 3.0
can I download the update package for this, thanks.

In July this year, I bought Norton 360 and installed it in my Laptop.

In October, my Laptop crashed and I had to re-install the OS once again.

Now I am in a dilemma, I cannot re-install the Norton Antivirus as I have misplaced the CD along with its product key.

Can anyone tell me how to re-install the Norton 360 again without having to pay another subscription for a new installation or download
