Subscription & Registration

Avast Pro Antivirus, Avast Internet Security, and Avast Premier can be downloaded and used free of charge for a 30-day trial period. After the trial period, you must purchase a license to continue program service.

Avast premium products, such as SecureLine VPN, Cleanup, and Passwords Premium, also require a paid license.

Licenses can be purchased for single or multiple computers, and for 1, 2, or 3 years.

You can purchase a license from the Store section in Avast, or at the official website www.avast.com.

After purchasing a license to renew or upgrade protection, you must activate the subscription on each computer covered by the license.

• Automatic activation - Directly after purchase in the Avast Store click Activate license to use the license on the same computer, if Avast Antivirus is already installed.
• Manual activation with activation code - If you haven't activated the product during purchase you will need to insert an activation code manually. Read more...

  Note: If you manually activate Avast Antivirus or an Avast premium product using an activation code, be sure to enter the code into the correct product's field.

• Manual activation with license file - You can also use a valid license file for older versions of Avast Antivirus, available from your Avast Account or the Avast license center.

Save the license to your computer, open Settings ▸ Subscription, and click Insert license file. Then select the saved file in the window which appears.

If Avast does not accept your license, follow the steps below:

1. Use our webform to resend your license to the e-mail address used for your purchase and try to insert the license into the program.
2. If the license insertion fails, uninstall Avast using the Avast Uninstall Utility and restart your computer.
3. Download and install the appropriate product version of Avast related to the purchased license.
4. Once again try to insert the license into Avast.

If you did not receive your purchased license, you can request it via our webform with the e-mail address you used during purchase.

If you have activated the Ongoing Protection Service (Auto-Renewal), your subscription is renewed automatically when your current license is due to expire. You are notified in advance via email.

You can manage the auto-renewal option for your order either by contacting Avast online customer support directly, or by following the instructions in these articles:
