How to show similar product with main product

[tablain]

Hi,

 

I have products line in that each product have different level.

For example take software line:

 

x antivirus have 1pc 1 year, 1 pc 2 years, 2 pc 1 year

(description and other details same just change in price)

 

And

 

x antivirus have premier and standard version

 ( description and details very much in common just few add up - also price change )

 

Also

 

Y antivirus have some top up features

  ( main product is same but top up modules have different job like prestashop system )

 

I am stuck how to do such feature on my site ?

Please help with your professional knowledge.
