Data Execution Prevention
The computer is mounted with the CPU supporting Data Execution Prevention (DEP)
technology (or a memory protection feature) built into the Windows operating system.
With the DEP technology, the operating system marks some memory regions as non-
executable and prevents execution of malicious program code there, which will result
in protecting the computer from virus infection.
•
Only the members of the Computer administrators group can change
the settings of DEP or the Security Center.
•
With the computer connected to LAN, the settings may not be changed.
Consult your network administrator.

protect your computer, Windows has closed this program,” close the message window
and check out the safety of the program and computer by following theses steps.
