Hi, sorry for the offtopic, but I will like to share my two cents I am using oneplus with RR 7.1.2(oms supported or you can say oms support added), with rooted with magisk, with substram theme engine, as matter of fact I am using Norton AV which has machine learning technic ( whatever that is) it always detect malware when I try to apply substram theme. It always says malware detected please see the screen shot added. By the way I already informed them about it as false positive but still they did not rectify it. Sorry to mention this AAT the last of the sentence actually Norton detected the injection, modifications, unwanted behaviour by any apps clearly, so in today's context you are using rooted device or not
You required this kind of av to look after the behaviour of the apps even your are installing it from play store because so many rouge apps gets approved and installed million time after million infection somebody found it, it is a rouge ware especially apps like games, themes, icon packs and whatnot. Anyway take care. Rooting the device is not problem but but using a rouge ware application like lucky patcher or similar kingo root applications to root the device is bad idea, your are inviting bad people with red carpet called hacked back doored invitation to your device. So morale of the story if you know what your doing do it or else stay in stock do not open the flood gate and blame everybody and everything else.
