I hate seeing this kind of thing, whilst this may be a small percentage of all of those going to iYogi and experiencing this hard sell, if it is one, it is one too many. This practice needs to be stopped and anyone found using it sacked. Either that or iYogi should be terminated.
For me the first port of call should be the forums, as there is no vested interest (not on commission/bonus, etc.) other than to help other avast users.
