We had a long running bug in McAfee which was causing our software to crash whenever it was working with SSL and some system .NET code deep in the bowels would somehow cause an AD lookup, which got intercepted by an injected McAfee DLL which crashed and took our process with it. We found it by attaching WinDbg and finding this dll on crashing threads’ call stack. Disabled McAfee, problem solved. We opened a ticket, they never fixed it while I worked on the project. In the end we dumped Windows as a platform since customer IT would never sign off on deploying a server image without AV, and rewrote everything in Java, deploying using Linux containers, where IT has no power. Cheaper, faster, less crashy.
