摘要：The modern computer virus was conceived and demonstrated by Fred Cohen in 1983. Like biological viruses, computer viruses reproduce by attaching to a normal program or document and taking over control of the execution of that program to infect other programs. Early viruses could spread slowly mostly by floppies (such as the 1986 Brain virus), but the Internet has made it much easier for viruses to move among computers and spread rapidly. Networks have created a fertile environment for worms, which are related to viruses in their ability to self-replicate but are not attached to other programs. Worms are particularly worrisome as standalone automated programs designed to exploit the network to seek out vulnerable computers. The term worm was originated by John Shoch and Jon Hupp during their experiments on mobile software at Xerox PARC in 1979, inspired by the network-based tapeworm monster in John Brunner's novel, The Shockwave Rider [1]. Shoch and Hupp thought of worms as multisegmented programs distributed across networked computers.
