Norton Internet Security 2010

Hi.

I was helping out my mum the other day with her computer security and I happened to find a (still sealed) norton internet security 2010.

 

I am therefore wondering:

 

Is this software still viable? She needs good protection, considering the work she is doing.


If it is not still viable: is it possible to "upgrade" this liscense to a newer one? That would, of course, be our prefered course of action.
