Aim AdHack is an antipublicity protection tool, that works to effectively eliminate all adverts and publicity banners from your AIM messaging client. It works with AIM 6.0 and later.
To use it, you don`t have to do anything directly with the program. Just extract the AIM Ad Hack file from within the same directory where you installed your AIM. It is also completely free. Not much more to ask for, really.
