[Avast User Guide for Taiwan]

1. Avast does not have a customer service center in Taiwan, nor does it have a customer service phone number. All customer service (including questions about product usage and refund requests) should be handled through the only official customer service channel: the Avast website. https://www.avast.comSelect "Support" at the top of the webpage and fill out the service request (currently only English is accepted).

2. In accordance with Avast’s global service policy, Taiwan-based retailers and distributors are only authorized to provide sales services; they are not authorized to provide technical support or refund for renewals. If you have previously purchased a renewal through the Avast website or app, please contact the website support team directly.

Avast products purchased through Taiwan channels will not automatically renew; please be sure to log into your account before activation to confirm whether the renewal has been canceled or the linked credit card has been removed.

4. If you are renewing your subscription, please first log in to your Avast account to confirm that the automatic renewal has been cancelled, and then purchase a new license from the Taiwan authorized channel. Enter the new license and complete the activation (please be sure to wait until the expiration date to enter it).
