Question

Is there a 3rd party company that tests and certifies your software for being trustworthy? I have a software that I made, but I believe not many people will download it if they have doubt about it being malicious. The software doesn't contain any malicious code. I want to provide proof of some sort to present to people so they trust my application and aren't hesitant to download it.

I'm not talking about virus scans btw.

Don't think so, anyone cheap won't be very trusted ;/
