How to prevent virus in mobile phone?

How to prevent virus in mobile phone? 1 1. Don't accept strange connection requests easily.

Now many mobile phone viruses have the function of automatically searching Bluetooth system. If your Bluetooth is turned on and searched, and you accept its request, then if the transmission is successful, the mobile phone virus will quickly erode your mobile phone and destroy it. So, it's okay, don't turn on Bluetooth, and don't accept strange connection requests.

2. Don't download things online.

Nowadays, the Internet is multifarious and has everything. Some viruses are hidden in these, and if you download them from a garbled website, the chances of poisoning will be even greater. Choose a website that is popular enough.

3. Delete suspicious messages

If your mobile phone receives some abnormal numbers, don't open garbled text messages, or your mobile phone will suffer. It should be deleted immediately to avoid infringement.

If you are not careful, your mobile phone will be poisoned.

First of all, you can format your mobile phone, but after the crash, any virus will say goodbye to your mobile phone, but some information in your mobile phone will be lost. So I suggest you go to the next antivirus software to kill the virus. If it is similar to the mobile phone version of Tencent housekeeper, it will be effective.

5. Insist on systematic antivirus of mobile phones every day.

To ensure that the software on the mobile phone is zero infection, you can also scan the payment security first to see if there is any payment risk.

Multiple conditions are met at the same time to get an electric shock.

Generally speaking, when a mobile phone is charged, it needs to meet multiple conditions at the same time.

① The charger leaks electricity and leads the dangerous voltage to the 5V grounding terminal of the mobile phone power supply;

② The mobile phone has a metal coating or a metal edge, and the metal edge is connected with the ground wire;

(3) the human body touches the metal edge, and other parts of the body are grounded, forming a loop to the ground;

(4) The household leakage protector fails or doesn't work at all;

⑤ When electric shock occurs, there is no one nearby to rescue and cut off power in time.

It is a myth that "a strong current will be generated when charging".

The transmitting power of the mobile phone will increase at the instant of power-on, but it has no special influence on the safety of electricity use. The rumor that "strong current will be generated when charging" is not true. According to the control of technical standards and enterprise norms, it should be safe to use mobile phones and chargers together, and there is no problem in charging and answering phones under normal circumstances.

When charging, wet hands will not get an electric shock when answering the phone.

Even if it is charged, wet hands will not get an electric shock when answering the phone. Because all chargers that meet the 3C standard have passed the humidity experiment, and the humidity environment reaches 93%, then the high-voltage experiment will be carried out soon. The input end of the charger passes the 3000V high-voltage experiment to the output end, and the input end to the shell ensures the isolation between the primary stages, and the high voltage will not be output to the mobile phone end.

Inferior chargers are dangerous and hidden.

According to WD/T 159 1 standard, the no-load power consumption current of the charger does not exceed 150 mA, so if you buy a regular and big brand charger, even if it is plugged into the socket for a long time, it will not be dangerous, but it will not save energy.

However, experts pointed out that there are many inferior chargers in the market, which can not meet the safety requirements and are prone to danger. So remind users not to buy too cheap chargers and look for the' safety sign' on the chargers.

How is the explosion of mobile phone caused?

The so-called "cell phone explosion" is actually caused by batteries. If the battery has quality problems, the battery will be short-circuited, the electrolyte will vaporize, and the battery will explode.

Cell phone battery explosion has nothing to do with long-term charging. In the battery safety test experiment, the output voltage rises when the battery is fully charged for 7 hours. Because the battery itself has a protective circuit, there is no explosion danger.

Battery explosion has nothing to do with charger mixing.

At present, mobile phone chargers adopt international standards (as long as they are qualified products), and the danger lies not in who exchanges them with whom, but in whether they leak electricity. In addition, the iPad charger with an output current of 2, 1A can completely charge the iPhone and other devices.

Some regular battery manufacturers will set directional pressure relief valves on batteries as the last protective measure. In case of danger, the gas generated by electrolyte gasification can be deflated to prevent explosion.

How to prevent virus in mobile phone II. Mobile payment involves operators, banks, third-party payment platforms, merchants and many other subjects, and user information flows in all links, so we should pay attention to the following four points:

Latent viruses and Trojan horses. The virus Trojan hidden in the mobile phone will get the user's personal information, automatically identify and block the user's payment SMS reminder, thus starting to infringe on the user's interests.

It is difficult to distinguish between true and false applications. Some fake applications are difficult to identify, and users' information will be uploaded to the server to transfer users' funds.

Phishing messages are gullible. Liars will send short messages to nearby users through pseudo base stations, fake banks or e-commerce customer service numbers to defraud users of all kinds of sensitive information and steal bank card funds.

Pay attention to QR code payment. Unknown QR code may hide virus Trojans or phishing websites. Once the scan is not careful, the wallet is dangerous!

Although there are many traps in mobile payment, we cannot do without the convenience it brings. I also summarized the following eight points for your study:

Buy a mobile phone through formal channels. Incorrect mobile phones are cheap, but they may be implanted with Trojans or viruses. Buying regular channels of mobile phones can reduce security risks.

Protect it with a password. Mobile phone boot password, software registration password, payment password ... all kinds of passwords should be set well, and one password should not be universal to prevent easy theft.

Download genuine application software. Be sure to download genuine mobile phone software to prevent criminals from stealing information.

Pay attention to abnormal text messages. When you receive a short message with the contents of "invalid password" and "bank upgrade", you must not click on the link easily, but call the official to verify it.

Regularly remove mobile phone garbage. Cleaning the mobile phone regularly can not only expand the memory of the mobile phone, but also find hidden software. In addition, be sure to delete important information such as ID photo and password text from your mobile phone.

Don't use unfamiliar WIFI to pay. When paying by mobile phone, ensure network security, and don't use WIFI in public places or unfamiliar WIFI.

Be sure to unbind your mobile phone number before logging out. Be sure to unbind all services before canceling the number! For example, bank card business, third-party payment platform, financial business, WeChat, Weibo, QQ, etc.

Don't throw away your old mobile phone at will. Don't throw away the old mobile phone as domestic garbage. Be sure to completely remove the data to prevent recovery and sell it to a relatively regular manufacturer.

Develop good habits and nip in the bud. While mobile payment is becoming more and more convenient, we should also be vigilant, protect the safety of funds, and prevent scammers from having an opportunity!
