Dri*avg technologies

Dear all, as AVG has made it more or less impossible to get in direct contact with relevant/responsible persons I turn to you. I have a an AVG virus protection program since many years back. It works fine and the annual subscription is paid i November every year. But on top of this AVG has added an invoice on 89,99 EURO, which is referred to as DRIAVG TECHNOLOGIES on by bank account without any further information. 
Is there anybody in this community who might know what this payment might be for OR how I could get in touch with someone in AVG who could help explain what DRI
AVG TECHNOLOGIES is good for? Warm regards Thorsten (retired and tired)
