If you did not activate Avast Pro Antivirus during installation or you want to activate your subscription on a secondary PC:

  2. Scroll down to the Installation Instructions section of the email and copy the activation code. If you are unable to locate your activation code, you can find it in your Avast Account:
  3. Right-click the Avast icon in your system tray and select Subscription information.
  4. At the top of the Subscription screen, click Insert activation code.
  5. Type or paste the previously copied activation code into the box and click Activate.

After the activation code is accepted, the text Your products were activated appears. Information about your subscription such as the expiry date and number of days remaining is also visible in the Antivirus section of the Subscription screen.

You can activate your subscription on the number of PCs you specify when you make the purchase. For example, if you purchase a subscription for three PCs, you can use the one activation code to activate Avast Pro Antivirus on three PCs. The number of PCs your subscription is valid for is specified in your order confirmation email.

If you need to transfer your subscription to a different PC, uninstall Avast Antivirus from your PC before you activate your subscription on the alternative PC.
