TIMA Detection of Unauthorized Kernel Modification
If the security system in the device has detected that the Linux kernel code has been modified after the device was turned on, you may see notifications "The device has detected an application attempting to perform actions that are not permitted. It is recommended that you restart your device."
This notification will appear for the following reasons:
• You installed a malicious application or virus, which modified the kernel code or the file system.
• You modified the file system of your device and removed or modified a system file.
Restarting your device restores the kernel code back to normal. However, note that modifications made to the file system (for example, factory settings file) cannot be restored. You may continue to see this error after the reboot.
Restarting your device does not provide a remedy for the actual reason the kernel or the file system was modified. It is recommended that you check for malicious programs, viruses, and malware.
