Charged $5?? Is this a card verification?

Hi, i got the free trials for Avast Internet Security and Avast Cleanup Premium. Cancelled them both so i don’t get charged in two months time. But i still have a $5 transaction that has showed up on my card??

Thanks for the quick reply. But I would like to know if this is a card verification or not. I cant find this in that link
