garg.vyom on "The site ahead contains malware Shows with red screen"

Hi my website anandpursahibfoundation.com shows The site ahead contains malware with red screen in Google chorme and Mozilla Firefox. I don't know where this malware come from. I found a virus named setup.php in every folder and sub-folder. So i deleted it. But nothing happened. It still shows with this red screen and written with The site ahead contains malware.
