There are also so-called “benign” PC viruses, such as the Cruncher virus, which compresses any infected file and thus creates space on the hard disk. In contrast, the aim is to improve security measures so they can withstand the attack of a PC virus that has more malicious intentions in the future. In addition, there are “well-intentioned” viruses, whose programmers* aim to discover security holes in the systems of certain companies or even in governments. However, other computer viruses that emerged over the years were designed to inflict extreme damage on their recipients. The first known viruses, such as the Creeper virus (1971) or the Ika-Tako virus, were programmed simply to annoy people or draw attention to themselves. However, the first computer viruses in history were comparatively harmless. How is a computer virus created and what is it used for? First of all, computer viruses do not develop on their own, but are programmed, usually to deliberately damage computers, systems or even entire networks. Unlike so-called computer worms, a computer virus usually only spreads locally, much more slowly and therefore causes less damage overall. In the process, the end user often suffers data loss or even damage to the hardware. What is special about viruses, compared with other forms of malware, is that they can spread to your PC without your consent.* A computer virus infiltrates other computer programs and spreads to infect other systems, and it can cause changes to the operating system or damage to other programs. How does a computer virus really work? Technically, a computer virus is a self-propagating computer program.
While today Fred Cohen is not a hacker, but a researcher and professor of computer security at the University of New Haven in West Haven, the viral code he developed laid the foundation for many dangerous computer viruses known today. It could penetrate other applications and programs almost unnoticed and then spread to other machines.
The origins of the computer virus can be traced back to Fred Cohen, an American who programmed the first PC virus in 1983.
In the worst case, a virus can cause a complete system failure. The word virus comes from Latin and means “poison” or “slime.” Unpleasant as these terms are, they well describethe consequences when a computer virus infects your PC.
