Advanced Security offer

Just read about the Advanced Security package , three month free trial and then £35 a year.  

I have used the Virgin Media F-Secure Internet package for years, and just renewed it for another year at £25.  Question .....does the new Advance Security package include what is already in the existing Internet security package, or is it an add on ?

if I opt for the new Advance Security package, what do I pay ?
