Mb9x.exe appears to be loaded from a autorun.inf on a portable usb drive this replaces the command shell and stops you lookung at hard drives. there appears to be a variant on ee1j.exe they appear as system, hidden read only files on the root directory of any hard drive or removeable drive and infect any writable drive inserted into the infected computer.
