That is strange since there are no files with those names inside the game as far as I know, unless it is part of the engine. Can you share the hash of the scan? perhaps I can identify what it is flagging.
Also for which platform are you downloading?
EDIT: Nevermind, those are AVs, not files.
Flagging from few AVs is not a very reliable detection, more often than not is a false positive. I can tell you we do not put malware on the game, but if you trust us or not that is for you to decide. In case of doubt, run the game sandboxed or don’t run at all. Stay safe on the internet :).
