I think I used the download from gofile, but I am not sure. I had the game runnning already, saw by change a post in the thread about this, and ran a specific scan by the antivirus (Avira), and got this message. Deleted the file, just to be on the safe side.
It is a generic trojan dropper warning, so, I guess if the game did online updates sometime it can confuse the antivirus, however, as far as I know this game does not do any online updating, so it seems nonteheless suspicious.
P.S. In case you wonder, the mods told me to report the potential problem in this way, so don't complain about me posting this in the thread
