Antivirus apps are unnecessary on android.

First of all get a proper custom ROM, it is well known that Xiaomi is sending out private data.

Well, he said he was unrooted, so no way for him to change his rom for a custom one.

Some people said google is blocking the magisk module via latest patches (I have red it from Reddit Forum)

Check every apps permissions and activity after download and before installing. Security vendors or antiviruses are pointless when modders can add permissions u cant change and grant full access to your device. Their is no need for viruses when they can just add permissions noone thinks to check. These are modders and hackers they aren't taking the time to mod these apps and post them on here for free without getting something from you it's very easy to code an app to run activities in the background without you ever noticing very easy to add permissions no one thinks to check when all they check is if an app has a Trojan or virus there's no reason for those anymore it's all about Android's permissions that the user grants full access to. protect yourself and do your research. just think out of the very few moderators on mobilism you really think they're taking the time 24/7 365 in front of their computer every single day checking the hundreds of thousands of apps that are uploaded they're not robots they have lives too and there's not enough of them to review each and every single app these modders don't give a f*** about you and neither do the moderators just do your research and use your head a VPN won't save you either from these permissions don't download the mobilism app either sick of people blindly getting f***** by this forum everybody's saying they haven't gotten malware or spyware or data stolen they have they just don't know it

... it is very risky, if you have personal data on android device (photos, contacts, communications, accounts, payments)...
