My mobile phone number has been used to send harassing messages. Is my mobile phone poisoned or the number has been used?

You can connect the mobile phone to the computer, open the toolbox in Tencent Computer Manager, then open Tencent Android Mobile Manager in the toolbox, and install Tencent Mobile Manager on the mobile phone according to the prompts. After installation, you can kill virus with one click.
