Thank you for your quick answerIt's a false positive and the launcher is perfectly safe. This sometimes happens after we update the launcher to a newer version as AV programs don't always keep up with the change and it takes a few days for them to register it.
With Norton AV, every major game update make me re-add it to the allowed programs. Sometimes it is the launcher, sometimes the game exe.Thank you for your quick answer
I'm aware of this latency between AV software and other apps, but its the first time it happen to my AV.
Until then, I just deactivate the "Behavioral Protection" while playing the game.
