Android Marshmallow 6.0 Uninstall problem

I have a problem to uninstall Avast A-T from my Moto G 3rd gen and Android 6.0.
Using article https://www.avast.com/en-us/faq.php?article=AVKB214#idt_110 I stucked in section “What should I do if the uninstallation of Anti-Theft does not work?” On screen shows up text “Settings application stopped working”
And that’s it nothing else from article works. Phone rebooted many times.
Avast Anti-Theft ver 4.1.2
Please help

both methods (preffered and alternattive) doesn’t work. I have to disable anti-theft from Settings → Security → Device admins. When I try It, I have error: Application Settings Stopped working…

I would say reboot the phone and try again.
Not saying it will solve it, but it is a easy thing to try.

Problem solved. Avast A-T doesn’t have right priviliges. I had to turn on Settings → Security → Advanced → Monitoring Applications → Avast Anti-Theft → Turn ON

It is early here, but I like to read good news :smiley:
