Subscription renewal

I have removed AVG products from my PC and gone to another company. However I still get emails from AVG saying they are going to access my credit card in July to renew. Other than cancelling my current card and going to a new one with a new number, how do I stop AVG making such an UNAUTHORISED charge on my card?

Michael,

You can cancel Auto renewal process to stop this payment. We see that your AVG Internet Security - Unlimited is up for renewal. Would you like to cancel auto renewal process for this product?
