Repeated antivirus failures combined with continuing malicious traffic indicate that the malware may have persistent components that cannot be reliably removed through standard cleanup. ECIH eradication principles require restoring a compromised device to a known trusted state when the responder cannot guarantee that malicious components have been eliminated. A factory reset or clean reinstallation of the mobile operating system removes applications, configurations, and persistence mechanisms that may continue surviving conventional antivirus scans. Switching to airplane mode is useful as an immediate containment measure because it interrupts communications, but it does not eradicate malware. Disabling the SIM card similarly affects cellular connectivity while leaving the infection intact, and restricting background refresh has no meaningful effect on deeply embedded malicious software. Therefore, reimaging or reinstalling the mobile operating system is the appropriate eradication step.
