Remove Duplicate Account

I have created another account on my new PC and wish to remove the account under another gmail address from my old PC to avoid duplicate billing. I wish to also replace the new account email on my iphone as well.

Hello Ken,
I have sent you an email, please reply to that email with your both email addresses and also confirm which email address you want to have AVG MyAccount with.
Best regards,
Alok.
