Game not starting after latest patch 1.2.5

After the latest patch that released today, 1.2.5, the game does not start anymore. every time I click on start in Steam, it says in a steam message: The process for Kingdom Come could not be started. Access Denied (0x5).

Okay, I figured out why. My antivirus software keeps detecting the .exe as an infected object which it then “disinfects” instantly, causing it to not work anymore. Which is kind of weird since it never happened on any other game.

Similar stuff happend to me with other games. By default I always set en exception for the folder where games are stored,so the antivirus ignores them.
