One of our machines had had FrontMotion's Mozilla Firefox Community Edition deployed to it via a group policy, this install was also listed in Add/Remove Programs. This was then uninstalled, also via group policy and disappeared during a successful removal from Add/Remove Programs.

However, the SDP asset scan is not seeing the software as removed, it sees no software changes on the machine. Why is it not seeing the removal of the software and how can I correct that?
