I don't know the name of this one, but it kept coming back after being deleted.
MSRZ.EXE
KNJBO.DLL
IEJL32.DLL
IEJL32.EXE
the last two were in the Windows\System32 directory
i got rid of this little booger by terminating the running processes listed above PLUS explorer.exe .. then i used a batch file to unattrib system and hidden flags on the above files AND delete the filth !
