Files are protected against intrusion by badly behaving programs. An embodiment may define a file association between a kind of file on an operating system, and a program which normally opens that kind of file. An operation is detected whereby another file attempts to change the file association. When that happens, a recommendation is provided to a user of whether the user should change the file association and allow said different program to open the file. One embodiment may determine if there is another program which is masquerading as said file-associated program and prevent the masquerading program from opening the file.
