Abstract: A system, method, and computer program product are provided for determining whether code is unwanted based on the decompilation thereof. In use, code is identified and the code is decompiled. In addition, it is determined whether the code is unwanted, based on the decompiled code.

Abstract: A naming system, method and computer program product are provided. In use, unwanted code including at least one attribute is identified. In addition, an encoded name is generated for the unwanted code, where at least a portion of the encoded name represents the at least one attribute of the unwanted code.

Abstract: A system, method, and computer program product are provided for generating a file signature using file characteristics. In use, a plurality of characteristics of a file is identified. Furthermore, a signature for the file is generated based on a combination of the characteristics.

Abstract: A system, method, and computer program product are provided for determining whether code is unwanted based on the decompilation thereof. In use, code is identified and the code is decompiled. In addition, it is determined whether the code is unwanted, based on the decompiled code.

Abstract: A system, method and computer program product are provided including identifying a network communication and determining whether the network communication is initiated by a process associated with unwanted code. As an option, a firewall may identify the network communication and computer code may determine whether the network communication is initiated by a process associated with unwanted code. As an option, in one embodiment, a method may be provided whereby unwanted code identified by network communication may be quarantined and/or the process associated with the unwanted code may be terminated.

Abstract: A communication system includes at one end of a communications channel, a first cipher generator for generating a succession of ciphers, the generator including a first random number generator for generating a sequence of random numbers, each cipher of the succession of ciphers being based on a respective successive portion of the sequence of random numbers, and a symmetric encryptor for encrypting successive amounts of information for transmission to the other end of the channel, each amount of information being encrypted using a respective one of the succession of ciphers.
