The invention relates to a method for detecting malicious executables, which comprises: in an offline training phase, finding a collection of system call sequences that are characteristic only to malicious files, when such malicious files are executed, and storing said sequences in a database; and, in runtime, for each running executable, continuously monitoring its issued run-time system calls and comparing with the stored sequences of system calls within the database to determine whether there exists a match between a portion of the sequence of the run-time system calls and one or more of the database sequences, and when such a match is found, declaring said executable as malicious.
