Feral Heart

When i try to download Feral heart in the game setup my computer always screws up when i try to download it, so first i press Download. Than after that it says 'FHSetup (1).exe' appears malicious. I pressed the arrow on the side and pressed keep, so for a few seconds it looks like it's downloading.. And after that i open it says that the file is corrupted and it closes. I don't know if it something i downloaded. I thought Winrar 32 was messing with it, so i uninstalled it but the problem keeps
coming.

I have a Windows 7 if that helps anything..
