I want to ask if there is a virus on your mobile phone. Mobile phone automatically sends text messages, networking ~

First, the concept of mobile phone virus

Mobile phone virus is also a computer program, which is as contagious and destructive as other computer viruses (programs). Mobile phone viruses can be spread by sending SMS, MMS, email, browsing websites, downloading ringtones, etc. Cell phone virus may cause the user's cell phone to crash, shut down, delete data, send out spam, make phone calls, etc. , even damage the hardware such as SIM card and chip.

Second, the types of mobile phone viruses

Mobile phone viruses can be divided into four categories according to virus forms:

1. Viruses "kabir" and "Lascaux". A "transmission via Bluetooth device, no red transmission.

Little knowledge:

Cabir is a network worm that can infect mobile phones running Symbian operating system. After the virus is found in the mobile phone, it will use the Bluetooth wireless function to scan other mobile phones with loopholes nearby. When a vulnerable mobile phone is found, the virus will copy itself and send it to the mobile phone.

Lasko Like a worm, the virus spreads wirelessly to other mobile phones via Bluetooth. When the user clicks on the virus file, the virus is activated immediately.

2. Mobile phone virus "Mosquito Trojan" of mobile communication provider.

Little knowledge:

The virus is hidden in the cracked version of the mobile game "Mosquito". Although this virus will not steal or destroy users' data, it will automatically dial and send a large number of short messages to numbers located in Britain, resulting in a sharp increase in users' information fees.

3. The virus "mobile phone hacker" for mobile phone bugs. Little knowledge:

"Mobile phone virus. SMSDOS "can be spread by SMS or MMS, resulting in errors in the internal programs of the mobile phone, which leads to the failure of the mobile phone to work normally.

Third, the spread of mobile phone viruses.

1. Spread via Bluetooth

From June 5438 to February 2004, Kapoor virus was discovered in Shanghai. The virus will modify the system settings of smart phones, and automatically search whether there are loopholes in neighboring mobile phones through Bluetooth and attack them.

2. Infect the mobile phone executable file on the PC

On June 5438+1October1day, 2005, "Velasco" virus was discovered. After the virus infects the computer, it will search the SIS executable file on the computer hard disk for infection.

3. Use MMS multimedia message service to spread.

On April 4, 2005, a new way of spreading mobile phone virus appeared, which was spread through MMS service.

Fourth, the target of mobile phone virus attack

1. Attacks Internet content, tools and services that provide services for mobile phones.

2. Attacking WAP server makes WAP mobile phone unable to receive normal information.

3. Attack the control "gateway" and send spam to the mobile phone.

4. Directly attack the mobile phone itself, making the mobile phone unable to provide services.

Five, the prevention of mobile phone virus

1. Scramble SMS and MMS, and delete.

Scrambled SMS and MMS may contain viruses, so delete them immediately after receiving them to avoid being infected with mobile phone viruses.

2. Don't accept strange requests.

When using Bluetooth, infrared and other wireless transmission functions to receive information, you must choose a safe and reliable transmission object. If a strange device requests a connection, it is best not to accept it. Because as I said before, mobile phone viruses will automatically search for devices within wireless range to spread the virus.

3. Ensure the security of the download.

At present, there are many resources on the Internet to provide mobile phone downloads. However, there are many viruses hidden in these resources, which requires users to ensure that the download site is safe and reliable when downloading various resources with their mobile phones, and try to avoid downloading from personal websites.

Sixth, the removal of mobile phone viruses Now the best way to remove mobile phone viruses is to delete short messages with viruses. If you find that your mobile phone is infected with a virus, you should turn it off immediately. If it crashes, you can remove the battery, and then take out the SIM card and plug it into another model of mobile phone. 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.
