Changes in System Area

System area is a storage area that is used by system applications. It contains sensitive user data and data critical to device operation. If root access is not allowed on your device, the system area is not available to you.

Malicious applications can gain root access and make changes to the system area: delete, add, or change files or folders.

You can enable system area monitoring in the Scanner settings. If the component detects suspicious changes in the system area, it notifies you about it after the scan.

Change	Name	Type
Deletion of folder with files	read-only.area.dir.deleted.threat	Deletion of system files
File deletion	read-only.area.deleted.threat	Deletion of system files
Addition of folder with files	read-only.area.dir.added.threat	New files in system area
File addition	read-only.area.added.threat	New files in system area
File modification	read-only.area.changed.threat	Change of system files

If Scanner detects one of the changes listed, the files or folders themselves are not necessarily malicious. However, the change could have been made by a malicious application.

For the detected changes, the following options are available:

•Ignore.

•Send to laboratory (available only if executable files have been added or changed: .jar, .odex, .so, APK, ELF files, etc.).

•More on the Internet.

The component merely informs you about the changes listed above. To detect the malicious application that could have made the change to the system area, run the full scan.
