It’s been a while since I have this weird and irritating issue. Every few hours, I have to force quit KIS from Activity Monitor so it gets restarted and let’s browsers, Skype, Telegram Desktop … to work again or else network reachability is blocked for those.
When I got my MacBook Pro 2017, it came with OS High Sierra and I never had issues with it. an OS crash happened after an update of MAC OS Sierra and I had to upgrade to Mojave to be able to use the device again and after sometime issue started.
My brother have the same machine and OS and he also has the same issue as me.
1-I am using KIS 184.108.40.2069 fully updated on a long license plan
2-I am on MACBook Pro 2017 with OS Mojave updated to the latest
2-I did try uninstalling and reinstalling a freshly downloaded package from KIS download page
I have to say sometimes I feel KIS make the system run a bit slow.
