Companion viruses use a feature of DOS that allows software programs with the same name, but with different extensions, to operate with different priorities. Most companion viruses create a COM file which has a higher priority than an EXE file with the same name. Thus, a virus may see a system contains the file PROGRAM. EXE and create a file called PROGRAM. COM. When the computer executes PROGRAM from the command line, the virus (PROGRAM. COM) runs before the actual PROGRAM. EXE. Often the virus will execute the original program afterwards so the system appears normal.

A COM file is a type of executable file limited to 64 kb. These simple files are often used for utility programs and small routines. Because COM files are executable, viruses can infect them. This file type has the extension COM.
