After I downloaded a software, I kept sending verification codes and deduction information, but stopped sending them after about 10 days. I couldn’t detect the virus using Mobile Manager.

If you need to identify whether there is a virus on your phone, we recommend that you:

1. Some mobile phones support smart managers (memory managers), and you can scan the device through "Device Security". Check the device memory to find whether there are threats or malware on the device.

2. Download safer mobile phone security software and try scanning your phone.

If your phone detects a virus, it is recommended that you:

1. Back up important data (contacts, photos, memos, etc.) and restore factory settings.

2. If the above operations are ineffective, please bring the purchase invoice, repair card and machine to the Samsung service center for inspection.
