So i have downloaded this file before but i think this time it was a different link, its this show case of what unreal engine 4 can do (game engine) and i downloaded it from http://lucidarchi.tech/ its a rar extractor exe file so i run it its all fine and dandy it drops the executable file i run it and bitdefender detects it with active threat control, should i be worried? can someone check if this file is actually malicious or no,t its the pc version for who ever will check it.
