Feedback: Removal tool please

Well, I had a hard time finding CIS removal tool (if there is any at all) for my friend who bought avast internet security (yes, with firewall) because AIS and CIS conflicts with each other.
If there is not removal tool, I would like to request the developers to compile one, because it is simply too much time of manual cleaning with the computer (2hours of seach and destroy).
Thank you developers in advance.
