I am running fiddler as a proxy so that I can debug a webview on a mobile device. However when I run fiddler, it takes over my proxy settings (as expected) but never releases them. It adds certificates to my personal certs that are flagged as fiddler and it also modifies my proxy settings so even when it is not running, it says that I my system administrator has set my system to not allow me to change. After running Malware Bytes, I am able again to change my proxy settings.
This only happens after I run fiddler. Also this makes it such that I need to run Fiddler to do any localhost development on a web site. If I uninstall fiddler, remove the extra certs, and use Malware Bytes to remove the registry changes that it modifies, then I can run my localhost without fiddler. I am seriously considering that there is something extra wrong here but I think I will have to get a different proxy system.
