I, too, am having this issue. Windows 10 Pro Version 1803 (OS Buuld 17134.137) Chrome Version 67.0.3396.99 (Official Build) (64-bit) ESET Endpoint Antivirus 6.6.2068.0 SSL/TLS filtering is not enabled. Otherwise seems to be using default settings. I am not inclined to remove ESET, no matter what Chrome says. I will live with the warning as long as I can; if it becomes more obtrusive, bye-bye Chrome.
