App Locking no longer works

Samsung galaxy tab S
Android 5.0.2

Hello.

Over the last few days my app locking feature no longer works.
When I try to activate it....A box pops-up saying "you need to enable special permission in system settings" I hit settings and that takes me to wifi setting.

This worked fine up until a day or so ago....anyone know how I can fix it?

Thanks.

Hello,
we apologize for this Samsung specific issue. On Samsung devices we can't open correct Settings screen.

Pls,
1) Go to the Settings -> General -> Security -> Apps with access to usage data
2) Tap the "Avast Mobile Security" checkbox
-> "Allow access" pop-up is shown
3) Tap "OK"
-> "Avast Mobile Security" checkbox is checked and you can go to the Avast Mobile Security app and set App Locking
