Windows 10: security risks of installing and running applications whose publishers are 'unknown'

Is is okay to download a gameboy emulator from the internet? Do these apps pose a security risk to my files and privacy in any way that I should be alarmed about? The publisher of the 'mgba' application a gameboy emulator that I downloaded from the internet is 'unknwon'

Unknown Publisher when trying the installer(exe/msi) on windows 10

I'm using Visual Studio 2019 and have build "Installers(msi/exe)" using "Setup Wizard".

When i'm running the set.exe installer, the application "publisher" is being reported as "Unknown".

I've gone through some references and found that the setup.exe needs to be digitally signed with the certificate. So,

i have followed below steps to add digital signature to the setup.exe

1. Create Digital certificate (https://knowledge.digicert.com/solution/SO26065.html)

2. Using signtool i have digitally signed setup.exe

signtool.exe sign /f "E:\sample.pfx" /p "sample@123" /tr
Time Stamp Server & Stamping Protocols | Sectigo® Official /v "E:\setup.exeWhen
i try to run setup.exe locally, the application "publisher" is reported as "localhost" instead of "Unknown", but if i

run the same setup.exe on another system application "publisher" is reported as "Unknown"Please provide any suggestions on fixing this "Unknown
Publisher" issue

 

unknown publisher

Hey, J.K. Rowling was an unknown publisher before Harry Potter, and look what happened to her.

But in your case, the 'unknown publisher' refers to the security certificate that vouches for a software program. These certificates need to be renewed annually or they become invalid, and Windows won't run software with an invalid security certificate.
CM Tray is part of a very old program. Upgrade to the most recent version of the program, which will likely have a valid security certificate.
