I have been using adblock on all my devices espically on windows (primary pc) I know a Mac too on mac adblock had some problem with Mojave (I have report the issue). Coming back to the topic.Also on android phone I think it is the best adblock. My device is rooted so I take extra security precautions. These are the security stack I have been using on my android device and if your device is rooted I highly recommend using this stack
Adblock of course https://adblockplus.org/
1 password https://1password.com/downloads/android/
Kaspersky Mobile security https://www.kaspersky.com/android-security-free
Share your security stack for rooted devices too.
