There was a post in another forum stating that NBRT needs a wired internet connection for best results:
See item number 6, in this: http://malwaretips.com/threads/antivirus-rescue-cd-usb-bootable-tools-of-scanning-and-removal-of-malwares.32170/
What if making a physical wire to computer WIRED internet connection is impossible because of physical restrictions on position and wirelength of equipment? Would a wireless/wifi connection be possible?
Also, what is the proper naming: Recovery Tool, or Rescue Tool?
