Windows 10: How can i keep real time protection OFF?

I have this game which ran fine for a year on W7. Then i upgraded to W10 and it no longer worked. Tried uninstalling and reinstalling but every time it would give me an error and not start. I googled it and found the issue is the system will not allow a certain file and deletes it when u try and run the game. The problem is i can turn "real time protection" off which is the fix i found in many google searches, but the stupid protection will not stay off and when it turns itself back on it will just delete the file again. How can i turn that [email protected] thing off for good? I have kept all protection off because of things like this since i have been online in the late 90s and while i have had some issue i have always been able to fix them and it's worth the occasional virus or whatever to eliminate problems like this. So if anyone knows how to turn the thing off permanently please clue me in. I AM supposedly admin on my PC and i even try checking the run as admin box in the file before installing but it seems W10 just doesn't want people to have control of their own PC.
