ABSTRACT:
Various embodiments of the present invention provide elements that may be utilized for improved virus processing. As one example, a computer readable medium is disclosed that includes a virus signature compiled for execution on a virus co-processor. The virus signature includes at least one primitive instruction and at least one CPR instruction stored at contiguous locations in the computer readable medium. The CPR instruction is one of an instruction set that includes, but is not limited to: a compare string instruction, compare buffer instruction; perform checksum instruction; a seek instruction; and a test instruction. The primitive instruction may be, but is not limited to, an add instruction, a branch instruction, a jump instruction, a load instruction, a move instruction, a logic AND instruction, a logic OR instruction, and/or a logic XOR instruction.
