Lately, I've seen that a directory with what seems to be a random name (like
Z0tQWDVmQmoyRUxVSWdBU2pwNzAxMzc1Mw) is present in the local storage (
/sdcard) of my Samsung Galaxy S5.
When I delete it, it's automatically recreated.
The directory contains three files, two with random name and the third is named 'This directory is very important. Please do not delete.' One file contain some script or code to create an sqlite database and tables.
Could this be a virus? Is there a way to find out which app is creating this directory?
