Virus
A virus or computer virus ensures that software is manipulated, and thus great damage is caused. In this context, the term computer virus is derived from the virus of medicine. The computer virus behaves like the medical virus in that it installs harmful parts - in this case harmful software - on the affected system and damages it or, in the worst case, destroys it. In the process, the computer virus can also spread and thus damage or infect other systems. Computer viruses infiltrate software, operating systems, RAM, or boot sectors in order to have a destructive effect. The term computer virus also includes malware, Trojans, and computer worms.
