Android devices, this malware is usually in the form of an unwanted
screensaver that takes over your screen to display ads when charging
your devices. The DU screensaver malware in question is either called
Du Quick charge, DU battery boost, Du Battery charge and other DUs you
can think of. Although it isn’t malicious, I was really angry when I saw
it on my device some weeks back.

comes as a result of several app developers deliberately installing them
to make some extra ad revenue. Pending the time Google fixes this, the
only solution is to manually uninstall the apps. Now, thanks to the
list compiled with the help of a Google Docs spreadsheet started by Reddit user phincone, you can see some of the apps causing this:
- ES File Explorer (prior to the update)
- ES AppLocker
- Flashlight & LED Torch
- FotoRus – Photo Editor
- GO Keyboard
- GO SMS Pro
- GO Weather
- 360 Security
- InstaMag – Photo Collage
- KittyPlay Wallpapers Ringtones
- LOCX App Lock
- Next Browser
- Photo Collage Editor
- Photo Editor Pro
- PIP Camera-Photo Editor
- Share cloud
- Solo Launcher
- TouchPal Keyboard
- TrustGo Ad Detector
- UC Browser
- XBrowser
- XBrowser – Super Fast & mini
- Xender
- Z Camera
I must point out that ES file explorer updated their app to remove
the DU malware, but if you are still seeing it, you can either update it
or go to Es Explorer, Tools and disable charging boost. For
Xender, click on the little gear (Settings) icon in the top right
corner, you will see an option to switch off the Xender Quick charge
feature
