What about the prank virus in the mobile phone?

If you use a vivo phone, you can see how the phone was invaded by a virus:

1, enter the mobile phone, my housekeeper-security detection-scan and clean the virus;

2. It is suggested that after backing up the data of the mobile phone, go to Mobile Phone Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Clear all data (check the format of the mobile phone storage or SD card, please back up the important data in the mobile phone before this operation).
