Executable File Formats

An executable file is one that contains code which will run automatically when the file is opened. What this means is that the file executes (carries out, not kills) whatever set of instructions it was programmed to complete. This makes executable files ideal for deploying spyware or other malware as it requires the user simply to double-click on it to activate the malicious code contained within.
