I have avg internet security -for one year but it shows it will expire in twenty eight days why?

Hello Pankaj,
Please be informed that the license which you have provided is not valid with AVG. However, from your account I see that you have registered for AVG Internet Security - Unlimited one Month trial (Which will expire on 1/9/2018), which is why you are receiving trial expires pop ups.
Best regards,
Alok.
