Enhanced Virus Protection
From Wikipedia, the free encyclopedia
Enhanced Virus Protection, often abbreviated as EVP, is a proprietary technology used by AMD which attempts to prevent malicious computer code from being executed without the user's knowledge or permission.
EVP is a feature of CPUs, and it allows the operating system to designate certain areas of RAM as readable and writable, but not executable. By preventing the computer from executing code in areas that were not intended to contain executable CPU instructions, many buffer overflow attacks may be prevented.
