problem with new email on account

I have changed ISP’s and have a new email I was under the impression I had notified avast. I am not an expert at having an account that covers more than one device, as until now I haven’t had more than one. Now I have my original PC and added a laptop and an android tablet. Tonight I decided to see if Avast covered the other two and discovered I have 4 cleanups 2 for each address.
Also my pro antivirus is still in the old email address (iprimus), while my internet security is in the new (tpg) address. I have no idea how to sort this out or what is covering which device. Please Help
