Hi
Also regularly have the same problem with MACOS 10.14.6 and ESET Cyber security 6.8.300. I have noticed that this happened after the MAC has been suspended several times . I didn't try disabling web access protection but when this is happening (randomly) the only way to stop ESET using all CPU is to reboot. Then it works fine again , until next time.
I will then try to save the log and process activity next time it happens
