ACGuardian?
 

I recently notice a couple of online games exe protected with aspr 2.0. But there is something peculiar is that is that it have 2 copy of the process running with 1 copy protecting the actual process. It will create event with name like "AcGuardian" & "AcWard". There is also a filemapping created "AcSharedBuffer".

I suspect it is some sort of api/library based protector since the exe can be protected using aspr.

Does anyone know what is the actual name of this protection/protector, and the info about it? Thank you.
