We're glad to look into this and help you.
May I know, from where do you checked the used devices?
Did you check this on your AVG My account > Subscription?
If yes, please share the screenshot of the AVG my account - subscriptions page via email. As it is not recommended to share the subscription/order details over this public post. Hence, I've sent you an email to your registered email address. Please check and revert to us.
Thank you for your understanding.

我可以知道，您从哪里检查使用过的设备？
您是否在您的 AVG 我的帐户 > 订阅中检查了这一点？
如果是，请通过电子邮件分享 AVG 我的帐户 - 订阅页面的屏幕截图。 因为不建议在此公开帖子上分享订阅/订单详细信息。 因此，我已向您的注册电子邮件地址发送了一封电子邮件。 请检查并回复给我们。
感谢您的理解。

因為我已經續訂10部裝置。
但之前有裝置在別的PC。
幾乎是無法清除調之前的3部裝置。
