The message you are seeing is triggered by SmartScreen. On a pre Windows 8 machine, you will only see this if you use IE. On Windows 8, SmartScreen is enabled on the OS level. SmartScreen displays this warning based on your applications reputation score.
If you want to download this yourself, you should be able to fine the "Run anyway" option.
If you are concerned about what other people will see when they download your software, there are no easy shortcuts. You can:
- Sign your application with a certificate issued by a CA trusted by Windows (this will not make the warning go away, but makes it easier to accumulate app reputation, as it will give you the combined reputation of all applications you sign with the same certificate).
- Make sure your application is not being detected as malware by AV software (try using VirusTotal).
- Get your app certified by Microsoft. Running the Certification Kit is not enough. You must submit your results to Microsoft.
Over time, as people download your app, its reputation will rise, and eventually it will no longer trigger SmartScreen warnings.

1@Ramhound This is not exactly correct. Using a certificate signed by a trusted CA will accumulate SmartScreen reputation for the certificate (as opposed to just one particular binary) so the downloads of any of your applications will boost the reputation of all of them. The warning will still appear though (however the UAC will look less scary though. – lzam – 2014-09-11T00:43:48.840
I suppose I failed to mention there are other requirements not to get the notification but they are also published by Microsoft, so I didn't think, I needed to – Ramhound – 2014-09-11T00:50:31.650
