actions after pc format

Hello to all. I have a PC (desktop) which is working with windows 7 currently. I use avast internet security and avast cleanup premium. It is time for me to change to Windows 10. But after the installation of windows i will have to re install the avast programs. Any ideas- guidelines how i will do this re-installment of the avast programs ?

Thank you in advance for your time,help,answer .

Hi
When I upgraded to Win 10 I simply downloaded and installed the latest versions of programs and entered the license/s that I saved on a flash Drive for each program I installed and all went fineā€¦
