DEP is stopping me using the internet

Question

I am using Windows Vista Home Basic with I.E.7, and Norton 360.
Over the last 4 days, whenever I try to connect to the internet, I get the message that Windows DEP has blocked the connection for security reasons.
I have used remove/uninstall to remove programs that have been downloaded in the last few days, just in case it was these that have caused the problem.
I have also tried doing a System Restore a couple of times, to a time before this problem appeared, but got the message that the restore failed.
Has Norton failed to pick up a Trojan or a type of virus that is the root cause?
Can Windows DEP be disabled or the settings be reset ?
I can access the internet by using Safari explorer, so my router connection is ok.
Can someone out there offer a solution to this problem ??
Please.........................

Answer 1

Disable Data Execution Prevention (DEP) completely

Click Start, and then click Control Panel.



Under Pick a category, click Performance and Maintenance.



Under or Pick a Control Panel icon, click System.



Click the Advanced tab, and in the Startup and Recovery area, click Settings.



In the SystemStartup area, click Edit.



In Notepad, click Edit and then click Find.



In the Find what field, type /noexecute and then click Find Next.



In the Find dialog box click Cancel.



Replace the policy_level (for example, "OptIn" default) with "AlwaysOff" (without the quotes).



WARNING: Be sure to enter the text carefully. Your boot.ini file switch should now read:



/noexecute=AlwaysOff



In Notepad, click File and then click Save.



Click OK to close Startup and Recovery.



Click OK to close System Properties and then restart your computer.

This setting does not provide any DEP coverage for any part of the system, regardless of hardware DEP support.



Verifying DEP is Disabled



Click Start, and then click Control Panel.



Under Pick a category, click Performance and Maintenance.



Under or Pick a Control Panel icon, click System.



Click the Advanced tab.



In the Performance area, click Settings and then click Data Execution Prevention.



Verify that the DEP settings are unavailable and then click OK to close Performance Settings.



Click OK to close System Properties then close Performance and Maintenance.
