ABSTRACT:
A computer-implemented method for executing a computer file in a CPU emulator (154) to detect a computer virus. The method includes simulating (302) the execution of a predetermined number of instructions of the computer file in the CPU emulator (154), suspending (303) the execution, constructing (304) a state record, temporarily storing (305) the state record in memory, comparing (306) the constructed state record to state records stored in a state cache (158), and indicating (308) that the file is virus free when the constructed state record matches one of the stored state records.
