Viewed the list of applications that use Wi-FI and came across what is shown on the image below.
What it is? Virus? Instead of Google I use F-Droid. Root is there, but only Total Commander and Titanium Backup are available.
Phone - Samsung Galaxy J1 Mini.
Rooted, twrp.
In applications "10005" does not exist.
Titanium Backup was deleted 2 month ago.
After installing Dr.Web 10005 disappeared. But from 15.11.2018 to 12.12.2018 "10074" exist.
