My computer has become very badly infected , it stops loading many times and shuts down without notice other times. Please help me to get this cleaned up.

Hi,

Try this to reset the DEP issue



There are two area's that DEP is held

One in the performance section and the other in IE

Firstly we'll fix IE DEP

1. Open up IE and quickly select Tools
2. Select the advanced tab
3. Uncheck the Enable memory protection
4. Restart IE to apply.



1. Start\Control Panel\System and Maintenance\Performance Information and Tools\Adjust visual effect
2. Select the Data execution prevention tab
3. Check the Enable DEP for Essential windows programs and services
4. Restart the computer to apply.





Alternatively

Disable DEP using CMD

1) In the command prompt, type bcdedit.exe /set {current} nx AlwaysOff and press Enter.
2) You should get a success message back
3) Close the command prompt.
4) Restart the computer to apply.
