Data Execution Prevention-Security Feature of Windows

Data Execution Prevention (DEP) is a security feature that helps prevent damage from viruses and other security threats by monitoring your programs to make sure they use system memory safely.

If you choose to protect all programs, you can still turn off DEP for individual programs.

If you suspect that a program does not run correctly when DEP is turned on, check for a DEP-compatible version of the program or an update from the software publisher

before you change any DEP settings.
