What should I do if my Nokia 5800 phone has a SMS charging virus?

Install the security manager or 360 mobile phone guard, and then enter the program management (the name of the security manager is this, and there are similar ones in 360). After scanning the software installed in your mobile phone online, you will be alerted if there is malicious software, and then you can uninstall it. If you can't find it, update the virus database and kill the Trojan horse. Most malware can't escape the eyes of security housekeepers and 360 mobile guards.
