SafeZone lock up on Windows 10

Been trying SafeZone that came with the free version of avast and I have had a tab lock up that was running a lash app. The problem is that I can not close the tab, the browser, or even terminate the app with the Windows 10 task manager. So I have to reboot my PC to resolve this.

Any tips to solve this? I am more interested in the fact that I can not terminate the app with the task manager than the flash problem.

Thank,
Bob P.

You should be able to kill the task if disable the avast self defense first.
Ofcourse don’t forget to enable it again.
