Fiddler Ideas

Can't detect Bitdefender free AV connections

I installed Bitdefender Free AV web installer and Fiddler could not detect any connection made by it.


To reproduce, download it from here, open Fiddler, and then install the downloaded exe. Check Fiddler and it will not be able to detect anything from the installer.


If there is a way to solve this, please let me know. I'm using latest Fiddler in Windows 8.1 core 64-bit.

    It's not entirely clear what you're trying to do? If you're trying to see traffic from the installer itself, the two possibilities are that:

    1. The installer doesn't use HTTP/HTTPS at all, or 

    2. The installer is buggy and doesn't respect the system's proxy settings.


    If you're trying to do something else, what is it?

     Yes, I am trying to view the traffic from the installer. If what you are saying is happening, then is there any other way to view the complete urls that the installer is connecting?

    You could try using something like Wireshark or Microsoft Message Analyzer to watch the traffic at a packet level, but if HTTPS in use, neither is likely to be very effective.
