They got money from my carte without to ask me before!

Hello,
I realized that “Driavast sofrtware” -alias avast- took from my carte 72,99 E while I had already payed my annual subscription for ONE computer. They insisted that I need a 10 (!) computers subscription!!
Isn’t there anybody out there to stop them?

Have you looked here (Account and Billing) to request a refund:

or
