Extremely high background data usage

[BalconyJedi]

Hello all,

 

I've been using Malwarebytes Anti-Malware on my Moto G (2nd Gen) ever since I got it in June, running Android 5.0.2 (Lollipop). I usually keep cellular data switched off because I'm on WiFi a lot and only enable it when I quickly need to go online to check something. Yesterday I went on a 4:30 hour drive and used Google Maps for navigation, so I did switch on cellular data. Once I arrived, I noticed that Malwarebytes Anti-Malware had racked up around 90MB of background data during the drive, while Google Maps had used less than 40MB! I don't know the exact numbers since I didn't write down the usage before I went on the trip, but I think it shows clearly that something is off. I never left the phone on cellular data for an extended period of time, but I doubt Anti-Malware would usually leave such a huge data footprint.

 

Since I was using Google Maps during the whole drive, I assume it is somehow related, however, it might be a false conclusion. Does anybody have a clue what the reason might be? I'd like to avoid this kind of behavior in the future. For now I restricted app background data on cellular networks for Malwarebytes Anti-Malware but I don't want to be unprotected. See attached a screenshot of the data usage (showing the spike in usage) and as a comparison a screenshot of the WiFi data, where Anti-Malware seems to have used around 56MB of background data in the last 28 days, so roughly 2MB per day which seems fine.

 

What kind of information would you need me to provide? Here are my basics:

 

Moto G 2nd Gen, I'm with Consumer Cellular (in the US)

Lollipop 5.0.2

Anti-Malware v1.05.1.1000 (151)

Avast Mobile Security & Antivirus

 

Thanks for any ideas and have a great weekend,

Ben
