amd enhanced virus protection nx bit

Summary

AMD processors have additional protection from malicious software known as Enhanced Virus Protection (EVP). 1 This protection works by setting aside portions of memory as "data only". 1 The NX bit (no-execute) is a technology used in CPUs to segregate areas of memory for use by either storage of processor instructions or for storage of data. 2 This feature is increasingly used in conventional von Neumann architecture processors for security reasons. 2
