In Microsoft Windows operating systems, the "System32" folder contains files and information that make the computer, and any devices that are attached to it, function. This folder is so important to the health and performance of the operating system that in some cases, by default, the computer will request an administrative password just so a user can view the contents of the folder. Malicious software that infects a computer may be directed by their programmers to take over files in the "System32" folder, because taking over this folder is one of the keys to taking over the entire system.
