I have the same issue since about 2 weeks. I have transferted my account from Sierra MacBook Pro to new TouchBar MacBook Pro with Mojave. eset_proxy is using 100% CPU and no browser or mail software works. Try to uninstall / install ESET Cyber Security, seems work during several days and issue again. Killing eset_process is working during couple of minutes and need to kill it again regulary.
