Uninstalled ESET Security AV, Macbook could not connect to the internet

I accidentally uninstall ESET AV by throwing it and empty into the trash bin instead of uninstalling it using the uninstaller. After I restart my mac, I could not access the internet even though it can connect to the Wifi (Home router and Mobile Personal hotspot). Is there any way I can fix this?

1. Tried renew DHCP
2. Tried booting up in SafeMode (Issue still remains)
3. Reset network setting by deleting some config files

Is there any solution out there i can try to fix this issue? Thank you very much.
