EV code signing for Unity3d Game exe

Dear All,

I've built a game for windows platform. I'm sharing that with my colleagues. When installing/downloading/launching, it's been treated as risky file or virus and making the user not to download (web browser) or install (windows PC) this application. How do I solve this?
Is the code signing done by Unity engine? Please help. Thanks in advance.
