Fred Cohen invented a way for trojan software to be implanted in programs and infect computers.

He told BBC World Service's Witness programme about the day he made the discovery while studying at the University of Southern California 26 years ago.

Mr Cohen discussed the idea with Len Adleman, another computer security expert at the university.

His research led the way in protecting computers from the threats that surfaced in the years to come.
