Abstract
A computer implemented cyber security method for preventing and removing undesired modifications of a protected file may include: generating a virtual file object via an authorized handler associated with the protected file, and when a write request to the protected file is received, the write request is redirected to the virtual file object causing the write request to store the change to the data of the protected file as data in the virtual file object; receiving a read request of the protected file; determining if there is data on the virtual file object associated with the protected file; and determining if the data on the virtual file object comprises a change to the data of the protected file; and, based on the determination, the authorized handler returns one of: (i) the data of the protected file changed by the write request and (ii) the data of the protected file unchanged by the write request.
