First Virus & Antivirus
The First Malware, known as "Creeper" (not the one from Minecraft) appeared in the early 1970s. It was a self-replicating program that displayed a text reading, "I'm the Creeper: Catch me if you can!" It wasn't harmful but was made to test spreading across connected systems. The virus was eventually followed by a program called "Reaper" designed to remove it.
