When you purchase Avast Premium Security (previously Avast Premier) from within an Avast application, your subscription is automatically activated on the Windows PC you use to make the purchase. A subscription purchased through another Avast sales channel, such as the Avast Store, are also automatically activated when you receive and install the preactivated setup file. If your subscription does not activate automatically, you will need to manually activate using either a valid activation code (sometimes called a subscription code or voucher code), or via your Avast Account that is registered with the same email address you used to make the purchase. If you want to use your Avast Premium Security subscription on another device, you also need to manually activate it. The number of devices you can activate depends on the subscription you purchased.
