Acme (computer virus)
Encyclopedia
Acme is a computer virus
which infects EXE
files. Each time an infected file is executed, Acme may infect an EXE in the current directory by creating a hidden 247 byte
long read-only COM file
with the same base name. (In DOS, if the file extension is not specified, and two files with the same base name exist, one with .COM and one with .EXE, the .COM file will always be executed first.) Acme is a variant of Clonewar, a spawning virus. Acme is also perhaps a descendant of the small single-step infector Zeno, which is not to be confused with the Zeno programming language

Zeno programming language
Zeno is an imperative procedural programming language designed to be easy to learn and user friendly. Zeno is generic in the sense that it contains most of the essential elements used in other languages to develop real applications.The Zeno Interpreter was designed for use in Windows 95 and later...
