The Malware Museum is a collection of malware programs, usually viruses, that were distributed in the 1980s and 1990s on home computers. Once they infected a system, they would sometimes show animation or messages that you had been infected. Through the use of emulations, and additionally removing any destructive routines within the viruses, this collection allows you to experience virus infection of decades ago with safety.
I had a small collection of such disarmed viruses: around of 20 executable files by the late of 90-x. Unfortunately it was lost somewhere on the abandoned diskettes.
