So im new to using armitage and ive been having a annoying problem. I ran my OS scan on a improper IP and now my OS screen is filled with LINUX machines and then a printer. There is so many of these IP addresses and they dont go away when i close armitage. Every time i restart i get the same list and i have cleared the only job i was using. Is it possible to remove those IP addresses? Any help is greatly appreciated.
