I using macOS Mojave 10.14.5 and KIS 22.214.171.1244a.b.c.d.
It happens very frequently to have the scanning (let it be Quick or Full) hang at the same object com.apple.telemetry. I'm unable to stop the scan too. The only resolution is to restart the machine.
This issue was present on High Sierra too.

I think I was able to make Kasperky Internet Security work properly after Force Quiting (killing) the kav process using Activity Monitor, rebooting my Mac, then relaunching Kasperky.
Quick-Scans now complete in about 5-minutes, and Full-Scans take about 45 minutes. It's working now. Thanks.
