Basic knowledge of mobile phone virus

Mobile phone virus is a highly contagious and destructive mobile phone program, which can be removed by antivirus software or uninstalled manually. Once the mobile phone is invaded by virus, it will make the mobile phone users unable to use it normally. The virus relies on the vulnerability of the user's software system to attack the user's mobile phone.

Mobile phone virus is an infectious and destructive mobile phone program, which can be removed by antivirus software or uninstalled manually. It can be spread by sending SMS, MMS, email, browsing websites, downloading ringtones, Bluetooth, etc. , causing the user's mobile phone to malfunction and affecting normal use. So what are the mobile phone viruses? How to deal with mobile phone virus? Let's take a look at it next.

First, what is a mobile phone virus?

Mobile phone virus is a highly contagious and destructive mobile phone program, which can be removed by antivirus software or uninstalled manually. Mobile phone viruses can be spread by sending SMS, MMS, email, browsing websites, downloading ringtones, Bluetooth, etc. , it will cause the user's mobile phone to crash, shut down, delete personal data, reveal personal information by sending spam, automatically make phone calls, send short (color) letters, etc. , and even damage the hardware such as SIM card and chip, which makes users unable to use their mobile phones normally.

The software in the mobile phone, embedded operating system (the operating system solidified in the chip, generally written in JAVA, C++ and other languages), is equivalent to a small intelligent processor, so it is vulnerable to virus attacks. Moreover, short messages are not only simple words, but also information such as ringtones and pictures (92tO. Com), which needs to be interpreted by the operating system in the mobile phone and then displayed to the mobile phone users. Mobile phone viruses invade mobile phones by virtue of loopholes in software systems.

In order to spread and run mobile phone viruses, mobile service providers need to provide data transmission functions, and mobile phones need to support advanced programming functions such as Java. Many mobile phones with the functions of surfing the Internet and downloading may become the targets of mobile phone virus invasion.

Second, how to clean up the mobile phone virus

At present, the best way to remove mobile phone virus is to delete SMS or MMS with virus. If you find that your mobile phone is infected with a virus, turn it off immediately. If it crashes, you can take off the battery, and then take out the SIM card and plug it into another model of mobile phone (the brand of mobile phone is better to be different). After deleting the suspicious SMS stored in the SIM card, insert the card back into the original mobile phone. If it still doesn't work, you can contact the mobile phone service provider to disinfect the mobile phone through the wireless website or through the IC access port or infrared transmission interface of the mobile phone.

Because the communication use of mobile phones is still in the primary stage, the digital processing ability of mobile phones is not enough to handle and spread viruses independently. So viruses can only invade mobile phones through computers, WAP servers and WAP gateways. So as long as you pay attention not to answer strange calls and download mobile phone software from the internet as little as possible, there will be no big problem.

The prevention of mobile phone virus should adhere to the principle of combining prevention with killing. Don't check garbled text messages, download mobile phone software, browse dangerous websites, and accept infrared and Bluetooth requests from strangers. Once the mobile phone is infected with virus, you should choose professional and authoritative antivirus software to kill it as soon as possible. The recognized antivirus software in the industry includes 360 antivirus, security housekeeper, Tencent mobile phone housekeeper and other software.

Third, the harm of mobile phone virus

1. Once the mobile phone is invaded by virus, it will make the mobile phone users unable to use it normally. The virus attacks mobile phone users by relying on their software system vulnerabilities.

2. Mobile phone viruses mainly spread to our mobile phones through third-party software. We can avoid cell phone poisoning by avoiding receiving some spam messages of unknown origin.

3. More and more mobile phone users store personal information on their mobile phones, such as personal information, schedules, personal address books, various network accounts, bank accounts, passwords, etc. Some criminals will write various viruses to invade users' mobile phones and steal some important information.

4. If the mobile phone is infected with virus and forced to send spam messages to the communication network, it will inevitably lead to the congestion of the communication network information, and these spam messages will eventually paralyze the local mobile phone communication network.
