Hi Nihil,
Thank you very much for your prompt response.

I have found references to and explanations of regsvr32 in several locations.

THe confusion arises when I read a removal procedure, for example:
http://www.spyware-removal-guideline.com/aurora-removal

and it states that one must first UNREGISTER and then CLEAN the registry

So my assumption from this is that Unregister performs something different from mearly using regedit to remove an entry from the registry

What do you think?
