DEP (Data Execution Prevention) is a security feature that can help prevent damage to your computer from viruses and other security threats. DEP can help protect your computer by monitoring programs to make sure they use system memory safely. If a program tries running (also known as executing) code from memory in an incorrect way, DEP closes the program.
