Thanks for the reply but now my avg is showing it will expire in 23 days.Maybe the below facts can help.
When I purchased TUneUp I mistakenly inserted a wrong email in the registration for avg account. An agent helped through chat by correcting it so everything OK. I did received a serial but I don't know where to insert it.
I apologize for the inconvenience. This looks like a synchronization issue, I have escalated the case to the concern team to fix this. This will take some 5- 7 business days.
I have paid today for AVG PC TuneUp-Unlimited according to the invoice (downloaded AVG_Performance_803.exe file). I installed on PC, login successfully to my AVG account from my dashboard. However, the software still shows it will expire in 29 days.
