Abstract
To defend a computer against malware, first executable code, of the computer, that includes a signature that identifies an address, in the computer's memory, of a respective data structure that is potentially vulnerable to tampering, is identified. The first executable code is copied to provide second executable code that emulates the first executable code using its own respective data structure. The first executable code is modified to jump to the second executable code before accessing the data structure, and also so that the signature identifies the address of a guard page.
