Not that you need to read this, but: Nexus 7 2013 wifi, 4.4 installed from factory upgrade (not OTA), TWRP, rooted, SuperSU, etc. Had to uninstall MBAM, like everyone else reported here. The only other .apk failure was Xposed framework, necessary for experimental features in Greenify. If it helps at all, I am a ready guinea pig! Best from San Diego.
I've been a long-time user of several of the MB products on the PC. They live in my tray along with Agnitum AV & Firewall, WinPatrol+, etc. I own a rooted Nexus 7 2013, and just installed the mobile version: scanned and set up without a failure of any kind. Bravo! I know that the Android environment is VERY different than Windows, and there are far fewer toxins circulating. Do I need an additional AV, such as Avast, etc in the Android environment, or is the Mobile MBAM sufficient?
