I use AVG antivirus and when it detects a new program it is sent to their research lab. The installation passes / is aborted and a little later the response comes without a problem. The next installation paging goes without a problem. You do not say which Anti-virus program you use, but sometimes you can put programs on a whitelist.
The fact that your program is rejected every time seems to indicate that your program is apparently seen as a method that is "suspicious", or is vulnerable to abuse, or uses old libraries.
