Data Execution Prevention - Sharp PC-AL27 - Actius AL27 - Mobile Athlon 64 1.6 GHz Operation Manual

Data Execution Prevention

The computer is mounted the CPU 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 the 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 theses steps.
1. Open the Security Center and check the Firewall, Automatic Updates and Virus
Protection are ON.
