I need help!

[Neoman Seven]

I don't know why, but after some time, I tried to play the demo, and I got an antivirus message, flagging as a virus pua:win32/gamehack on the th19tr file, one time in the custom.exe, and another in th19.exe, I tried to delete it, and it keep saying it. I tried it in a virtual machine(in my friend pc) and it happened again, What should I do?
