Not sure if here is the right place to post this message.
I have a c++ program build with Visual Studio 2017. I uploaded the exe file to security intelligence, and got "No malware detected" for both client and cloud protection, but after a while when I clicked the "Rescan Submission" button, it instantly showed "Program:Win32/Wacapew.C!ml " under cloud protection.
The strange thing is, I uploaded the same file again as developer, it finally showed "No malware detected" after period of time waiting.
How could this happen, same file got different results, really frustrating.
