The mobile phone received a text message, and my friend said it was a decoration model virus.

It's quite possible. It is suggested to install a software to protect the mobile phone. I use this software, computer and mobile phone used by Tencent mobile phone housekeeper. Not bad. One-click virus killing protects your information from being leaked, which is safer. Similar to fraudulent short messages, you will be reminded directly when you receive them, and you don't need to identify them yourself, which is very convenient. You can also set one-click interception. Convenient and fast, can protect the safety of mobile phones. Fraudulent calls and harassing calls will be marked. I hope I can help you!
