When downloading in chrome, it auto deletes it cause it detects a virus
When downloading in firefox, it lets me download it, when extracting using 7zip, it auto deletes because it detects a virus
Please find out what is causing this and fix it

I have tried to use latest version of chrome to download the game and extract it with 7zip in two different computer, but can't reproduce the auto-delete circumstance. It should be false positive. I will check the build setting and see whether it can improved. Thanks for your remind.
