1 ) Remove Kaspersky.
I use the built-in Antivirus, with real-time control and the ability to choose between databases: Avast, AVL, and Tencent.
The other functions of KIS such as Block app, Call Blocker, block for privacy and anti-theft I got all from built-in features of ANDROID8/MIUI.
2) Replaced Adguard with Blokada
