it listens to ports apparently awaiting some signal I foun it because when shutting down windows thre was somting runnig and I needed to click end now when I listed the processes I found out it takes as much of my processor time as it can get so I selected my windows folder and searched for it found it in system 32 and renamed its file extension now it appears I have no more troubble
It often contains the trojan "Pakes.mzt" in various versions!
It takes a lot of the computer's Mem. usage.
this program registers .dll and .ocx files..It is a normal windows application! Do not delete, if suspicion of virus infects this executable then scan with software to repair. Removal will cause later future programs to install incorrectly rendering them with many errors upon install. ex.. (regsvr32 could not register GDIPlusWrapper.dll )
  Jesse Kilner  
It adds info to registry during software instalation, should -not- be running all the time...

This application is necessary for registering core dll files as well as for troubleshooting problems.
