Want to trace the source of virus that has infected your computer? Researchers at a Federal Institute of Technology in Lausanne (EPFL), Switzerland have the answer. The scientists have devised software capable of tracing computer viruses back to their source. Beyond computer viruses, the software can also trace terror suspects, rumor-mongering and even infectious diseases back to their source. Pedro Pinto, one of the researchers, explained that the algorithm works by going through information in a reverse direction back to the original source. He said, 'Using our method, we can find the source of all kinds of things circulating in a network just by "listening" to a limited number of members of that network.' The team tested their software on a known data maze to check if their research actually pinpoints the individuals behind the 9/11 attacks and they were able to pin-point three suspects, out of which one was the master mind behind the attacks
