There is no option in my Avast account as far as I can see that gives me the option to check if auto renewal is on or off. Maybe you can describe to acces that information there? The only thing I can see there is which product I have a license for and that my license is valid and it´s expiration date. Although it says on one of the avast/digital river sites that it can be managed from there as an alternative method. But there aint no such option. I contacted avast/digital river by mail and got an answer today that they couldn´t help me because it was a technical issue not a question of billing etc. So I did send a support request to avast support for help. Hopefully they can help.
