Data Execution Prevention
The computer features a CPU that is compatible with Data Execution Prevention
(DEP) technology (or a memory protection feature) built into the Windows operating
system. With DEP, 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.
Changing DEP Settings
By default, the DEP technology is enabled only for essential Windows programs and
services. To turn on the DEP for all programs and services;
1.
Click start – My Computer.
2.
Click View system information in the System Tasks field.
3.
Click the Advanced tab and the Settings button in the Performance field.
4.
Click the Data Execution Prevention tab and select Turn on DEP for all
programs and services except those I select.
5.
Click OK.
6.
Click OK in the confirmation window.
7.
Click OK to close the dialog box.
8.
Close the My Computer window.
9.
Restart the computer.
Checking Safety of Programs
As the DEP always functions on the computer against security threats, some programs
may be blocked to execute. If you have the message "To help protect your computer,
Windows has closed this program.", close the message window and check out the
safety of the program and computer by following these steps.
1.
Open the Security Center and check the Firewall, Automatic Updates and Virus
Protection are ON.
