(The anti-virus technology embedded in the CPU is a hardware anti-virus technology that cooperates with the operating system to prevent most attacks (mostly viruses) used for buffer overflow (bufferoverrun) vulnerabilities. Intel's antivirus technology is EDB (ExecuteDisableBit), AMD's antivirus technology is EVP (EhancedVirusProtection), but no matter what it is called, their principles are completely different. Strictly speaking, the anti-virus technology integrated in the CPU by various CPU manufacturers cannot be called "hardware anti-virus".)
