Turn off DEP (Data Execution Protection)

DEP (Data Execution Protection) is a software and hardware “layer” of security which prevents certain malware from running bad code to a non-executable memory section of the computer. It also protects against the bad code affecting programs or files from being messed around with and altered whilst they’re being stored in memory. However, DEP in all it’s goodness can sometimes cause problems with programs running such as Virtuozzo and other programs. To stop this:

  1. Click on Start , type in cmd in the search bar, hold Ctrl+Shift then press Enter.
  2. At the command prompt, type in bcdedit.exe /set {current} nx AlwaysOff
  3. You should receive a message saying Operation Completed Successfully
  4. Restart your computer; DEP should now be disabled

    Well I’m not Bill Gates but I would assume you turn it back on like this:

    bcdedit.exe /set {current} nx AlwaysOn
