I recently installed MalwareBytes on my tablet and it found Android/PUP.HackTool.DeviceAlive.a in /System/app/com.customermobile.nook.apk MalwareBytes says it can't delete it.

The file seems to be a part of a program called Nook Demo that's preinstalled.


I've tried factory resetting my Nook HD+ a number of times but after a few hours this keeps coming back is this a false positive?


These are the other antivirus programs I have tried and they all come back clean.


Avira Antivirus Security (Avira)

Bitdefender Anti Virus Free (Bitdefender)

AntiVirus FREE - Security Scan (AVG Mobile)

Antivirus & Security (AVAST Software)

Hi Bobber,


The "device alive" software is used buy sales people to be able to demo products, it allows customers and sellers to interact with all the

phone capabilities from the phone menus. They usually are bundled with a product for resale. We flag as a PUP because it could be used maliciously by the bad guys. Unfortunately you can't remove because it is preinstalled at the system level, but you can disable via Android's App Settings.
You can also whitelist the detection in MBAM Mobile by choosing 'Ignore Always" on detection.
