Is it because QQ cannot send messages that it is poisoned?

The failure of QQ to send messages is usually caused by unstable network. Please try to connect your phone to a WiFi network to send messages. The common symptoms after a mobile phone is poisoned are that the mobile phone automatically downloads other promotional software, freezes and becomes hot, and blocked advertisements appear. It may even intercept normal bank text messages, causing the user's account to be stolen, and the bank card to be swiped, etc. If you suspect that there are Trojans or viruses in your phone, please try to remove it by following the steps below:

Please try to install a security software (for example: mobile phone manager, etc.). Taking Mobile Phone Manager as an example, open the Phone Manager and click One-click Physical Check on the main interface to automatically detect problems on your phone and provide treatment suggestions. Click One-click Clear to delete virus programs.

If you are unable to solve the problem, please try to download the flash package and tools from the official website of the mobile phone brand to completely restore the phone. If you cannot handle it yourself, please send it to the official after-sales service of the mobile phone brand for repair.
