Hi Ivan,
We're glad to help you with the info.
You'll be able to use the free version without any validity. However, the program would show that it is valid for 365 days.
In that case, the program will automatically reactivate & it would be extended to another 365 days, after the existing subscription expires.
You can also manually mange it by reinstalling the free program.
For further queries, feel free to write back to us.
What s after free period is off? is AVG free fully functional?
Dandavat, Prabhudjee
