Sadly the launcher and even the game client get flagged but those are false positives. You have to either whitelist the executables or the whole folder, as long as you download them from the official downloads (aka the downloads page) you should be ok. I have an update planned for the launcher, to see if I can at least reduce the amount of false positives on it. The client on the other hand, there is not much to do about it... You will find the same issue in any psobb private serve
