Fred Cohen proved in 1984 that no algorithm exists to detect these entities.
Fred Cohen proved in 1984 that no algorithm exists to detect these entities. Veith Risak created an assembly language variant of this entity that was based on theories put for in a 1966 paper by John von Neumann. That paper introduced the theory of self-replicating automata. In the 1980s, a proof-of-concept version of this entity notably displayed the message "catch me if you can!" In addition to "Creeper", a more recent type of this entity has affected over one million computers and is called "Gozi". For 10 points, identify these computer programs that are targeted by Kaspersky Lab and McAfee, and which behave in a manner similar to their biological counterparts.
