Are you sure there is no virus? Windows protected my pc
it probably did that because the publisher didn't put a certain thing in the files of the game its nothing to worry about it happened to me many time before, when it pops back up just click more info and it will let you continue hope this helps
Yep no virus! :) We just aren't approved on windows yet/don't know how not to make that pop-up appear (if anyone knows let us know XD !)
