In the process of using computers, we often encounter some Trojan viruses, so what? I shared the method of killing Trojan virus by computer, hoping to help everyone.

Method one of killing Trojan virus by computer

Trojans use Jinshan first aid kit or 360 first aid kit. My solution is to enter the safe mode and use Kabbah to thoroughly kill and Jinshan first aid kit, then uninstall Kabbah, install NOD32 and 360 first aid kits, and enter the safe mode to kill and kill again. If this lineup doesn't work, Red Umbrella, Norton, Okumo, etc. The virus in cattle will not escape so many encirclement and suppression in soft kill! Unless you get a zombie virus! In that case, get a new computer.

Hehe, as long as people who have been online, I don't believe there are people who haven't been infected with the virus! Don't worry!

It is best to install a firewall, which will automatically intercept unknown files or attacks! And I will go to some small websites to download things less in the future.

Any virus exists in a computer in the form of a file. If you want to understand the virus, you should start with its basic existence. Then we can see where viruses usually hide. Because any virus and malware exist for a certain purpose, few viruses have their own independent directories like normally installed software.

First of all, we need to check all hidden files, because viruses don't tell you that they exist like ordinary programs. A good program developer should also think about how to make the virus live longer while developing the virus, so it is necessary to consider hiding the virus file. Nowadays, anti-virus software is constantly updating its virus database, but the emergence of viruses is always earlier than that of anti-virus software. Even now, it is considered that advanced active defense can only deal with threats with similar virus characteristics, but it cannot prevent the emergence of new viruses.

Secondly, if you look at the establishment time of a directory or file, you may find out where the poison came from. Nowadays, most virus files exist in the root directory of the system, which requires users to know the basic files and types of computers. But you need to carefully traverse all the disk characters. The file search function that comes with Windows can come in handy.

Although copied everywhere, this virus has only one main program file, and the file size must be the same. Open the advanced function of file search, fill in the EXE file type and enter the file size, and then press enter, and the virus hidden in every corner of your hard disk will be exposed. Using build-time sorting, you can find the first virus that attacks your machine. Now all the virus data files are in front of you, at least the virus can attack your main components, so please delete, delete all the virus-related EXE, DLL and data you find, but at this time there is a threat, because many viruses are disguised as key projects.

In addition, please be very careful not to delete files that are not viruses by mistake, which is a fatal error! Symantec's manslaughter was caused by deleting the key files of the system. Never restart the computer after dealing with the hard disk virus, which may lead to all previous efforts being wasted, because some viruses are not so easy to find. If some viruses do not appear in the form of EXE, but others, such as RAR, etc. Our file size search method is also applicable, just change the file extension. However, you need to be extra careful about viruses that are parasitic in the boot zone.

Second, further discover the virus.

Although the virus on the hard disk has been eradicated by us, there are still many things we need to do. Cutting grass needs to be rooted, so we need to modify the registry file, and the information of system services is stored in the registry file. The first thing you need to do is to carefully check your service list, and carefully check every undescribed service to see if it is related to the program you just completed. For users of Chinese version of Windows, virus detection service has certain advantages. The reason is ridiculous, that is, foreign programmers who write viruses don't understand Chinese, so they won't describe them in Chinese as system services. Therefore, we should also pay special attention to all services described in English.

Of course, many viruses now will be related to the key programs of the system. It will disguise the normal program of the system, or add its own connection to the loading project of the normal program. We can use tools such as ice blade and Kaka's internet assistant to judge whether the program item of the system is normal or not through HOOK. When we ensure that the program is safe, we can start to modify the registry file. First, check the registration items that are automatically executed when the system is started to see if there are suspicious programs. Except the normal software that needs to be started, delete all irrelevant startup items. The key startup program of the system itself will not be put into operation, but the service is the most critical for the system implementation. But when you find a virus here, don't delete the key value in a hurry. You should record it and see if the corresponding procedures have been filed by you. Then copy all possible names of virus programs, search one by one in the registry file, and delete all found matches. However, it is still dangerous to do so. It is recommended that you make a backup before modifying the registry file. After scanning the login file, you need to check the program list again, and then restart the computer to see if the virus will attack again.

Method 2 of computer killing Trojan virus

First, use antivirus software for antivirus.

First enter "safe mode"

How to enter: Press F8 before entering the Windows system startup screen, and then select Safe Mode! * * * This method applies to windows xp and windows 7***

Direct execution of anti-virus software killing, killing several times, the general virus can still be easily removed. If the killing is still invalid, or even the anti-virus software cannot be executed, please see the next method to remove the virus.

Second, use the system first aid kit for antivirus.

First enter "safe mode"

2. Here I recommend 360 system first aid kit and Jinshan system first aid kit. Of course, there are other system first aid kits. You can download more and try. Basically, some stubborn Trojan viruses can be removed.

Third, use virus killing tools to kill viruses.

Here, you need to judge for yourself what virus you are infected with and what will happen to your system after being infected with the virus, such as whether the countdown box pops up or the downloaded software is destroyed. According to these characteristics, you can search in Baidu or other search engines to see what kind of virus it is, then download antivirus tools, and then kill it, preferably in safe mode.

Four. System supply or reduction system

If there is software installed to restore the system, you can restore the system or reinstall the system, which can also kill virus. After reinstalling the system, it is better to use anti-virus software to kill or use the system first aid kit to prevent the virus again, which will be safer. Pay attention to enter safe mode to kill viruses. ?
