In 1983, Fred Cohen coined the term “computer virus”, postulating a virus was “a program that can ‘infect’ all  programs by modifying them to cover a possibly acquired copy of itself.” The term virus is in fact an acronym for Vital Information Resources Under Seize. Mr. Cohen broadcast his definition a year after in his 1984 paper, “A Computer Virus”, noting that “a virus can advance throughout a computer system or network using the authorizations of every user application it to affect their programs. Every program that gets adulterated may also act as a virus and appropriately the infection grows”.Computer viruses, as we know them now, originated in 1986 with the conception of Brain – the first virus for claimed computers. Two brothers wrote it (Basid and Farooq Alvi who ran a small software house in Lahore, Pakistan) and started the race between viruses and anti-virus programs which still goes on today.
Using the aloft explanation, it can be said that viruses affect affairs files. However, viruses can also affect assertive types of data files, mainly those types of abstracts files that support executable content, for example, files created in Microsoft Office programs that rely on macros.
Compounding the definition difficulty, virus also exist that authenticate a similar ability to affect data files that don’t about typically executable content – for example, Adobe PDF files, broadly acclimated for certificate sharing, and .JPG angel files. However, in both cases, the corresponding virus has a dependency on an outside executable and appropriately neither virus can be advised other than a simple “proof of concept” In other cases, the data files themselves may not be infectable, but can allow for the addition of viral code. Specifically, vulnerabilities in assertive articles can acquiesce data files to be manipulated in such a way that it will could cause the host program to become unstable, after which awful cipher can be alien to the system. These examples are given simply to agenda that virus no longer relegate themselves to simply infecting program files, as was the case if Mr. Cohen aboriginal authentic the term. Thus, to simplify and modernize, it can be cautiously declared that a virus infects added files, whether program or data. Computer virus are known as virus because they allotment some of the ancestry of biological viruses. A computer virus passes from computer to computer like a biological virus passes from being to person.
