W32.Induc.A!dr is a heuristic trojan horse detection for any files infected by W32.Induc.A. It spreads either with the updated version of Induc.A or in a legitimate installer, where it drops Induc onto the system. It is relatively uncommon, but this may change if Induc outbreaks around networks with Delphi installed on it. It was discovered 20/8/09 and affects all released Windows operating systems.
