What is Avast Care and why am I being charged for it?

I am wondering what this product is and why am I being charged with it, especially when I can’t see it under my subscriptions. I was automatically charged for it and I don’t know what it is nor do I even recollection when I subscribed to this product.

I’d like a full refund of the money taken from my account.
