Hello, Anita.
You have purchased a new AVG Internet Security - Unlimited (2 years subscription) instead of renewing your old AVG Internet Security (1 computer) license. Since the old license has expired, you might have received the automatic system generated notification to renew it. Please ignore that email. Unlike the older AVG, the new AVG Internet Security - Unlimited can be installed on unlimited no. of Windows and Android device. It also does not require a license as it is activated using your registered email address and password.
