Antivirus software, or antivirus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware.
Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other malware, antivirus software started to protect from other computer threats.
ORIGIN
Although the roots of the computer virus date back as early as 1949, when the Hungarian scientist John von Neumann published the "Theory of self-reproducing automata", the first known computer virus appeared in 1971 and was dubbed the "Creeper virus". This computer virus infected Digital Equipment Corporation's mainframe computers running the TENEX operating system.
The Creeper virus was eventually deleted by a program created by Ray Tomlinson and known as "The Reaper". Some people consider "The Reaper" the first antivirus software ever written – it may be the case, but it is important to note that the Reaper was actually a virus itself specifically designed to remove the Creeper virus.
THE FIRST EVER VIRUS IS -Creeper virus
THE FIRST EVER ANTI VIRU IS -The Reaper
Antivirus software acts as the final line of defense for your PC(S) and other devices. Which means it can protect – or at least mitigate threats – your devices when every other security software fails.
