I have what appears to be a 100% reproducible bug when installing ESET SmartSecurity 18.104.22.168 (64bit). When installing, I pick "custom" and when later asked about the "Filtering mode", I pick "Interactive". After installing the drivers, the installer stops progress in the very last part. The PC continues working, but all network traffic is dead. Shutdown of the PC works, and upon reboot, it immediately pops up the "new network found ... strict protection?" dialog. If I install with the default "Automatic filtering rules" enabled, it works every time.
