I have an invoice saying I automatically renewed my AVG Security on 8th April this year.  It doesn't run out until 23rd April!   I now keep getting these alerts saying it has run out and I am no longer covered.
When I try to activate … it says it is not recognising my licence number, even though I paste it from the one shown in the bar.  Not sure what else I can do.   I must have clicked the 'Activate' tab a dozen times and am getting nowhere !!
