Mobile phone automatically sends private messages. Is it infected by the "SMS thief" mobile phone virus?

Did you download a calculator software on your mobile phone, and then automatically sent an email when you went out to connect to the internet, and the content in the email was just some of your short messages? If so, your mobile phone is 100% infected with the "SMS thief" mobile phone virus, and your short message is likely to be spread by hackers. This kind of mobile phone virus is not difficult to deal with. You can kill it by downloading an antivirus. I have used NetQin mobile phone to kill viruses, which has a good killing effect on this kind of mobile phone virus that steals privacy, and the operation is simple. Download the software in the future, scan it with netqin antivirus to see if it is virus software, and it is rarely poisoned.
