I am a software engineer, with a lot of expertise in debugging this sort of issue. But it’s very hard for me to contact my antivirus developer and tell them they are blocking or interfering with a process erroneously when I do not have a good idea of what the process (Agent) is trying to do.
I can use (and am using) various pieces of diagnostic software to monitor what files and sockets it is opening and how they are failing, I can see the logs from Agent too. But that is no substitute for having the code in front of you and seeing what operations are failing. Your tool chain engineers will have to talk with Bitdefender about it. They are the only people who have the required information to do so.
I will keep looking at my end and trying things, I might get lucky by a process of elimination, but I may well not. Bitdefender is no small Antivirus, they have 8.5% of the market, that puts them in 5th place internationally. Will effect quite a lot of your customers.
