How to Solve blocked program issue when UAC ON?

[bluestar8783]

I will below manifest into my project and
I added string value into register:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
when packing installer by using IS2008(InstallScript
project)

After installing and reboot PC, when UAC on,
my program is blocked by Windows Defender.

Could I modify my AP or InstallShield to prevent
my program from being blocked?

Thanks for your help

You can try signing the file using a trusted CA?

Dear Sir:

Could you tell me how to signing my app(.exe) using a trusted CA?
Does it need to spend money?
