Since I accepted the lastest DEP (Data Execution Prevention) update in Antivirus FREE,
I am no longer able to run Doom2 computergame - I get "acess violation" error 
I use Windows 10 (danish version) and AVG Antivirus FREE also danish version
How do I revert the change caused by this update ?
Best regards,
Jesper Hansen,

Hi again Lathika,
I have tried to disable Antivirus FREE (see the screenshot below)
Where is that "resolve all" button you are refering to ?
The problem with Access Violation remains - it does not help to disable Antivirus FREE
Your software has made changes in my Windows's DEP settings (Data Execution Prevention)
Please connect me to someone who really knows about this, so I can revert the change, thank you.
