Mobile phone virus problem

Half a month ago, major media reported the first case of virus transmission between mobile phones. It is said that this experimental virus program named "kabir" has the function of spreading between mobile phones. At the beginning of 2003, this virus spread from computer to mobile phone has caused many people to suffer greatly, but now the appearance of this worm virus has further increased people's fear of mobile phone virus. So that once there is a crash, a black screen, and the address book can't be found, the owner will nervously think that his mobile phone is poisoned. Is the fact really that terrible?

Bug refers to a defect in the mobile phone itself, and a virus is a program that uses this defect to carry out malicious attacks or operations. Viruses are the cause, but bugs provide opportunities and channels for virus attacks. For this inherent defect, many manufacturers just quietly release upgraded versions of various softwares. This forces us ordinary mobile phone users to accept the test of the virus again and again.

At the beginning of 2003, it was reported that a virus called "mobile phone hacker" used bugs in the design of mobile phone chips to attack. It is precisely because of the unique defects that the releaser can infect the user's mobile phone through SMS. As long as the owner checks the SMS in the poisoned mobile phone, the mobile phone will automatically turn off. Some similar mobile phone viruses even cause failures such as automatic shutdown, crash, internal chip burning, mobile phone automatic alarm, personal phone book automatic forwarding and so on.

Moreover, the kabir virus mentioned above is only aimed at mobile phones using Symbian operating system, such as Nokia products, and many new mobile phones using Bluetooth technology to access modules. British Symbian once said that as of last year, more than 6.7 million mobile phones around the world used Symbian system. Bluetooth provides a certain range of mobile phone wireless docking, while Symbian system can transmit digital data.

Bugs are common, but viruses are not. According to habitual thinking, people pay more attention to rare things, so they ignore the inherent problems of mobile phone design defects and open the back door for viruses. Unlike computer products, our mobile phones have no special anti-virus software at present, and can only be exposed to the surrounding information environment. The appearance of the virus just sounded the alarm for us. On the surface, the era of mobile phone virus is coming. In fact, this crisis is caused by the constant emergence of mobile phone bugs.

How to distinguish bugs from viruses?

In fact, bugs and viruses are common problems when using mobile phones. Although they will bring all kinds of unnatural faults to mobile phones, they are very different. Because bugs are the defects of the mobile phone itself, they will only appear in specific mobile phones, models or specific operating systems. Although universal, it is not contagious. The failure is only within the product, and usually manifests as non-human phenomena that hinder the use, such as crash, shutdown or inability to execute specific programs.

A virus is a program that uses this defect to carry out malicious attacks or operations. It is written by a computer program and has the same spreading function as a computer virus. It can spread from the network to the mobile phone or from the mobile phone by sending ordinary short messages, multimedia messages, surfing the Internet, downloading software and ringing tones. The existence of virus will occupy the memory space of mobile phone, exploit the loopholes of the system or steal resources, or directly attack the system. In addition to non-human phenomena that hinder the use, the failures caused by it will also include deleting stored data, sending spam, making phone calls, damaging SIM cards and chips, etc., which will destroy the mobile phone system or communication network.

Because a virus is a foreign program, the biggest difference between it and a Bug is the stage of information input. It is more common to send anonymous text messages with programs. Once turned on, the system will be poisoned. If it is kabir, a virus that can spread between mobile phones, your mobile phone will use the network to send the same package to others when it is turned on or at work, thus infecting other normal mobile phones.

How to prevent virus invasion?

Let's talk about the virus problem first. Although as a general user, we can't completely solve the problem of virus infection by ourselves, but we can face it with the principle of treatment as the supplement and prevention as the priority.

At present, there are probably two kinds of viruses that threaten our mobile phones: one is a worm that has just come out and spread between mobile phones, but it is still in the experimental stage and will not go into it for the time being; The other is a virus message that has been sent. This virus is usually brought by short messages sent by hackers through computers. Generally, it has no effect on the mobile phone before opening it. Just like a computer virus email, if it is read, the virus will enter the mobile phone system and cause harm. Having said that, you must understand that being cautious about anonymous short messages is the best way to prevent virus attacks, especially short messages with strange or garbled sources.

Of course, some businesses are also actively developing anti-virus software for mobile phones. Virus vaccine can provide the functions of virus manual inspection, real-time inspection of downloaded files and automatic upgrade of vaccine functions according to user requirements, and provide basic virus prevention and control functions originally provided by computers, such as inspection record management. But unfortunately, this kind of thing is far from us, so it may be more effective to control your curiosity at present.

How to solve the Bug problem

Another important way to prevent virus attacks is to try to correct errors in mobile phones. Because bugs are not only a channel for mobile phone virus attacks, but also bring problems in use. There are many bugs, especially software problems. Let me give you an example first. 6600 is a relatively new model introduced by Nokia. In the earliest products, the simplified Chinese version of 2.35.0 software was used. Due to many loopholes, there will be problems such as the keyboard being locked for no reason, the number keys being invalid, and MP3 playing not listening. When upgrading to version 2.45.0, you will not be able to log in to GPRS normally, and you will find contacts in English, which will lead to the restart of your mobile phone. After version 3.40.3, although the search problem has been solved, there may be an error of insufficient memory when playing RM or 3GP, some wav files cannot be played, and even there may be insufficient memory when the system is running.

For this kind of problem, a better way is to upgrade the system, and you can know the latest software version through the service outlets provided by the merchants. If you don't pay attention to this problem often, take 6600 as an example, its software has been upgraded to 4.09.6438+0. As far as we know, the version of T628 has also been upgraded to R6C005, but in some places, T628 is still R6B02 1. It is said that even after upgrading to version R6C005, the menu speed will be much faster, but the background light can't be set to "off", the file in amr format can't be used as a ringtone, and the "Reject" list can't be edited when answering the phone. The latest version is still like this, let alone the old system.

I wonder if everyone already thinks their machines are out of date? But it doesn't matter, as long as you download the upgrade package and upgrade yourself, or go to a designated maintenance station to find a professional maintenance person to update the software, your mobile phone software can be "brand-new". Usually for genuine licensed mobile phones, such problems can be better solved by upgrading, but if it is a parallel mobile phone, it is another matter. In many mobile communication websites, we can see that many netizens post to reflect the Bug problems of mobile phones, many of which cannot be solved because of the parallel products used.

Several typical Bug symptoms

In addition to the phenomenon that we often encounter system vulnerabilities leading to crashes, sometimes imperfect functions will bring some inconvenience to use. Here are a few simple examples. If you encounter such problems, you can try to upgrade the mobile phone software, but we still suggest that you consult the maintenance stations of relevant manufacturers and let them solve the problem for you.

A friend had a phone crash when using Samsung SGH S508. The main symptom is that when the signal is weak, the system is easy to crash and the buttons are unresponsive. Usually it will return to normal after a period of time or a forced power outage, and there is a record of licensed parallel imports. In many cases, this problem may be caused by a serious shortage of system resources. At this time, pressing keys at will only increase the burden on the system. You can consider waiting patiently for a while, and if the system still doesn't respond, shut down and restart. Unplugging the battery when the phone is turned on has a great influence on the hardware of the mobile phone. I suggest you wait a little longer. If the phenomenon occurs frequently, you need to go to the maintenance station to check and upgrade.

In addition to the real crash, a few Sony Ericsson Z608 will also have the phenomenon of "suspended animation", especially when it is turned on. When encountering this problem, never turn it on or off or simply pull out the battery to restart it, which is not only useless to the mobile phone, but also can't solve the fundamental problem. After someone tries to start it, let it stand for a period of time, and the system will automatically run normally after about ten minutes. The reason may be system disorder or insufficient internal resources, and we can regard it as suspended animation. In addition to suspended animation at startup, Z608 sometimes suspended animation when operating the phone book. At this time, if you press the phone button crazily, all operations will be carried out when the system is restored. For suspended animation, it can also be achieved by upgrading.

When some models of Motorola V303 and Nokia play short films at high frequency for a long time, some users will jump screen. Although this phenomenon is not common, if you encounter this problem, you can try to edit short films with quicktime, which can generally solve it. This also reveals that these models fully support video files. Similarly, many mobile phones are also very picky about music and picture software. In this case, most of them can be changed into different formats, or re-imported into the mobile phone after editing with another software.
