Hi. I trust your tech team. I've watched the amazing remote access wonders many times. Could you just come on in to fix it w/ my approval? please? 
Hi, I think you may be referring to the option in Avast! of inviting a friend who also uses Avast! (and is also a forum member) to come in and work on your machine remotely, which is done by sending out an invite and the person targeted accepts. When this option is selected, a random code is generated that the user enters, and the other does the same, and the session between the two commences.
Is this what you meant?
As DavidR and Pondus say, this is a forum, and this is not the current practice of the malware specialists here. As this session would be private, between the two users, there would be no way to share the findings and results of that session as it progresses.
iYogi is no more, as DavidR says. iYogi was a free phone support, but the reported cases of misuse of user's trust was violated too many times, as the point of the support request was thought to be to get the user to purchase the annual iYogi support contract by some technicians there. It was supposed to be free, but was not for too many.
If you currently have a problem, please follow the guide here, and attach (do not copy/paste) the logs in your reply in this thread.
http://forum.avast.com/index.php?topic=53253.0 A malware specialist will be along shortly, you will be in good hands here.
EDIT: Interestingly, some of these iYogi technicians requested, and got, remote access to the user machines, and used their findings to state the user needed to buy the annual contract to get the help they needed. So, remote access can be a two-edged sword here, as your privacy and your system can be also be demolished by the wrong person. Oops!
