If you need to transfer your Avira license to another device, you’ll need to install the same product on the new device. However, in order to avoid a conflict with your license, please first uninstall the product from the previous device.
The easiest way to access your Avira license for the reinstallation, is to log into your account at this location.
Once inside your account, you can click on the “Devices” option on the navigation bar to the left to manually uninstall the license from any device it is currently installed on. Then, you can click on the “Subscriptions” options, followed by “Activate new License” to finally reinstall the license on the new device.
