Windows Defender deleting exe RRS feed

  • Question

  • I'm facing an issue while installing an application on windows 10 enterprise edition. After installing application windows defender detect it as a threat (Trojan:Win32/Azden.A!cl) and delete it's exe from installed location which is Program Files (x86)\Application Folder, this hasn't been observed in windows 7 and previously everything was running fine. I made this application myself and used VB.Net and Framework 3.5 to build this.

    Furthermore I observed the behavior of Windows Defender and windows update mechanism, my analysis is that Windows defender is most vigilant after installing new antivirus and anti spyware definitions, because in most of the cases Defender marked an exe as a threat right after Windows defender update.

    I solved this issue by recompiling the source without any change and on the same development environment and distributing the new exe. But I'm still confused what caused the exe to be marked as a threat in the first place and why it is working fine after recompiling, any help in this regard would be appreciated.

    Regards
