Payment taken without subscription

Can you help i have had two payments £84.99 each (last year and 1 pending this year) from AVG, but i don’t have any subscriptions or product purchases with AVG?
I have contacted my bank to cancell the payment, cancelled my card and blocked future avg payments.

What’s happening, why am i recieving these payment requests?
And why have a recieved no email to explain the payment?
