How to cancel trial version

Hi Folks,

A got a message that my AVG Tune-up Trial Version is becoming liable to payment in 7 days, so I wanted to cancel it. However, in the Subscriptions Section this Tune-up Trial Version is not shown, so I couldn't cancel it.

Can anyone give advice how I can go about before they start charging money? 

Thanks in advance,
Wolf
