I am having difficulty merging my linked email accounts that I used to purchase Avast Products, Licences, Services. For instance, I was trying to troubleshoot conflicts with Avast Premier and previous Avast installations. I received email from Avast Support to purchase uninstallation product to clean all Avast installations from my computer. I also have Avast Internet Security, SecureLine VPN, Clean-up Premium, Passwords, and others. My original Avast account is through Microsoft Outlook email on my computer. Other Avast purchases are through my Google gmail account. These accounts have links. Now it’s getting lexpensive and confusing. HELP !!!
