Virus total is giving 8/55 false positive for my exe build. But incase of msi buld, it doesn't show any infection. How can i remove those false positives without manually contacting AV companies. Is there some issue with AI signature or any best practice I can use to remove those false positives ?
I have tested your scenario but i can not reproduce the results. It is possible that one of your files may produce the false positive detection.
I strongly recommend you to submit to the antivirus vendors your built setup packages so they will whitelist it. This is a best practice and this way you will avoid such unpleasant detections. Nowadays the antivirus heuristics is changing on a daily basis and they become more and more aggressive. The best solution to avoid such false detection is to whitelist all of your built setup packages.
