What is Data Execution Prevention?

Data Execution Prevention (DEP) is a security feature that can help prevent
damage to your computer from viruses and other security threats. Harmful
programs can try to attack Windows by attempting to run (also known as
execute) code from system memory locations reserved for Windows and other
authorized programs. 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.
