Adam Riley, riley (at) avast (dot) com Avast Third-party Support Manager, has requested info about iYogi, so if you have time to recount your experience (copy and paste your post, etc.), give the link to this topic.
If you feel that you were pushed into the contract and that you are no longer happy, you should be able to get a full refund from iYogi, by saying you are going to proceed with a charge back action.
