History of Computer Viruses, The

A Bit of Archeology There are lots and lots of opinions on the date of birth of the first computer virus. I know for sure just that there were no viruses on the Babbidge machine, but the Univac 1108 and IBM 360/370 already had them ('Pervading Animal' and 'Christmas tree'). Therefore the first virus was born in the very beginning of 1970s or even in the end of 1960s, although nobody was calling it a virus then. And with that consider the topic of the extinct fossil species closed.
