I have put together a bare-bones test case which literally does nothing but FiddlerApplication.Startup(8877, true, true); and even with this after clearing the personal store of FiddlerRoot.cer, i'm getting a bunch of random FiddlerRoot.cer sometimes as many as 10 instantly being inserted into the current users personal store. Here is a screenshot of what happens when running the test case and refreshing a web page.
Ultimately it causes Fiddler to spam the error below to my log output:
