Hello, you can deal with the following two methods: 1. The built-in software is infected with viruses and the phone is not rooted. It is recommended that you go to Virus Scan - Settings - Virus Isolation Area to isolate the built-in risk software; 2. If non-built-in software is infected with viruses, you can go to Settings-Security-Device Manager of your phone, check if the virus software is activated in Device Manager, deactivate it and then uninstall it.
