Moving a subscrition to a new computer

Can anyone tell me how I can move my Avast subscription (automatic updates) to a new computer. I believe that my subcription is four three computers, but the fact is, I will not be using my old computer once I have the necessary information moved from it. Any assistance would be appreciated.

Uninstall avast from the old computer then install a fresh copy onto the new computer, once you have avast installed then either transfer the license to the new computer via a usb drive if you saved it or open the license email that was sent to you from the new computer.
