We have already seen how Data Execution Prevention, a security feature can help prevent damage to your Windows 10/8/7 computer from viruses and other security threats. Harmful programs who try to attack Windows by attempting to execute code from system memory locations reserved for Windows and other authorized programs are stopped. These types of attacks can harm your programs and files. DEP can help protect your computer by monitoring your programs to make sure that they use system memory safely. If DEP notices a program on your computer using memory incorrectly, it closes the program and notifies you. It is a security feature.
