For security, you can change to another anti-virus software. Different anti-virus software has different virus databases, anti-virus engines, involved parties, physical examination items, and different software engineers. The understanding of system vulnerabilities is different

Try Tencent Mobile Manager.

Tencent Mobile Manager can check and kill a large number of mobile phone viruses. The virus database will also be automatically updated in the WIFI environment. You can directly click "Security Protection" in the Mobile Manager interface and then select Virus Checker. To kill, just click virus scan at the end, and the protection and anti-virus effect is still very good.

Secondly, some require ROOT to clear them

Open Tencent Mobile Manager (PC) - App Store - Toolbox - One-click ROOT
