In most cases, viruses are attached to executable files. Sometimes they may be attached to other executable formats such as DLLs and overlays. Or they will be attached to a drive's MBR. That is the Master Boot Record and that does contain executable code at the end of a disk parameter table. The point is, the code has to be executed in order to cause an infection.For the most part, media files cannot get infected, and if there is virus code in them, the player or viewer will consider the files corrupted and either try to play/display the corruption anyway or abort with an error. There are a few exceptions such as the few media files that allow executable code or scripts to be attached.

Where headers files are generally stored?
It depends on the header file and on the general organization of the project. System header files, such as stdio.h or windows.h, are stored in a directory that the compiler knows about, but that you don't need to even think about. Library header files are either stored in the same place that system header files are stored, or they are stored in a place reserved for the particular library. In the latter case, there will usually be build parameters that identify the header files and their associated library files. User header files are either stored in the same directory as the source files, or they can be stored in a related directory, somewhere in the project directory tree. well in most of the DOS/Windows C/C++ compilers predefined header files are stored in INCLUDE directory of the folder containing the compiler
