Who knows how to prevent malicious charges from being deducted by viruses? Many of my friends can't get the business message of 10086!

It's simple. Just don't install software and surf the Internet. Haha, I think it's impossible. You are MM, don't worry. Don't blindly go to websites you don't know, and you won't say what mobile phone you are. If it is Android, try to avoid installing some applications that require the permission to send SMS. Also, it is best to install a professional mobile phone security software. I installed Wang Qin, which is very easy to use. I recommend it to you. If you think what I said is good, send me your mobile phone number quietly.
