AVG Internet Security

I purchased Unlimited Internet Security in November last year but on my 3 devices I have 3 problems ie. Firewall driver not found, online shield not active and email scanner not fully functional.   How do I fix this?  Also do I have to also purchase a tuner to to keep up to date?

Thank you
Mary Martin
