Game keeps resetting

Every time i launch wow it pops up with the windows defender prompt to ask i want to launch the game, doesnt save my login information and always launches in windowed mode, not a massive issue its just annoying having to change to full screen everytime i launch the game.

Never used to happen but i recently re downloaded and its happened since

Follow these steps:
1) Restart your PC
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only"
