Cancel the payment

Hello, Sherry.
You have subscribed for a 60 day trial version of AVG Internet Security - Unlimited on 19th Feb 2018. The authorization charge of 1.00 amount may appear to verify the validity of your payment method, but the amount will be reversed. It is just a payment authorization, money is not technically debited. May I know how much was the amount appeared on your statement for this transaction?

According to my recent credit card statement, I made a payment to "DRI*AVG TECHNOL SHANNON, CO. IE".
However, I don't remember I made this payment before, and  I don't want to keep using AVG.
Please help me cancel this payment. Thank you.
