Cancel the AVG driver updater

Dear support,

I was trying to cancel the AVG driver updater, since I am not using it but it got message:

Hmm... Something went wrong

Sorry, we couldn't unsubscribe you right now, but don't worry. It's probably a one-off bug. Try again, and if it still doesn't work, please contact our support for help.

Could you please check?
Thanks and kind regards,
