system problems

Everytime I want to start the game it tells me that it might be some dangerous stuff and it can damage my software, so I click that I want to start it anyway. Then it everytime make a game screen really small and all the way resets my whole sound and video settings. It's annoying to edit all these settings over and over again.

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"

Thank you so much for help.
