'''Acme''' is a [[computer virus]] which infects MS-DOS [[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 MS-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 instead of the .EXE file.) Acme is a variant of [[Clonewar virus|Clonewar]], a spawning virus. Acme is also perhaps a descendant of the small single-step infector [[Zeno virus|Zeno]], which is not to be confused with the Zeno programming language.
