Computers have improved our work efficiency and enriched our lives, but at the same time, computer viruses have also brought us endless troubles. Once a computer is infected with a virus, if it is normal, you can just rely on the antivirus software on the market to "set it down" it in a few seconds. However, if you encounter those difficult viruses, it will not be so easy to deal with. Sometimes, although you are deeply accustomed to the virus, the antivirus software on your machine is "kind" and often stops when you click, showing mercy to others, and cannot bear to kill it. As a result, most of the viruses are driven away, but a small number of the viruses are still in love with them and are "bringing children" there. At this time, are you sighing at the poison or want to completely eliminate it, eradicate the roots and then quickly? I think you will definitely choose the latter, so how can you do this?= All rights reservedHot Network Hot downloads
1. Use multiple antivirus software to take turns to prevent viruses.
Since different types of antivirus software have different focuses, each with their own strengths and weaknesses, it is best to take turns to check and kill multiple antivirus software. In this way, not only can we play to our strengths and avoid our weaknesses to give full play to the advantages of our respective software, but we can also cross-check and kill viruses, with excellent results. After my computer was infected with the virus, I only used one antivirus software to kill it at first, but it was not completely killed. Later, I used Rising, Kingsoft Anti-Auto, and Xingtian 98 to check and kill it, and it was completely eliminated.
Tips: Download multiple shared or trial versions of antivirus software online, which not only saves some money, but also because they are all used as templates for everyone to use, the effect is not worse than the purchase. However, some have usage periods, such as Kingsoft Antivirus, the trial period is 30 days. In addition, when downloading, you should pay attention to downloading on a regular website. After downloading, you should check for drugs, and pay attention to whether there are conflicts, stable operation or unstable operation, etc.
2. Make careful preparations for various settings in the antivirus software.
Usually, when an antivirus software is run for the first time, its default antivirus settings cannot meet our needs, so we must set it accordingly due to the "toxic" conditions.
⑴. When you cannot determine the nature of the virus, you should select "All files" in the "Search and Kill Settings", including "Search and Kill files, include subfolders, check unknown macro viruses, and clear unknown macro viruses (all macros)". In this way, the inspection and Kill can be more comprehensive and in-depth, and avoid missing killing.
⑵. If you already know the nature of the virus, you should selectively make settings in all aspects. If you already know that your computer is infected with "happy hours", you just need to check and kill the "htm, html, http, and asp" files. This not only speeds up the speed of virus detection and killing (this setting is particularly suitable for some computers with a large number of files), but also avoids killing some easily damaged files, such as WORD files, causing unnecessary losses. If you are afraid that doing this will cause missed killing, you can first use multiple antivirus software to use this Dharma to check and kill it in turn and then conduct a comprehensive "sweep" of all files.
3. Boot the system with a clean disk and perform anti-virus in DOS mode.
After killing in Windows environment, you must also check and kill in DOS mode so that you can more thoroughly remove viruses on your computer. Nowadays, many people only focus on anti-virus on Windows operating systems. Just forget it after killing, and ignore the importance of clearing and killing in DOS mode. In fact, many viruses and computers with deep poisoning must be cleaned in DOS mode, especially boot viruses. Therefore, after you have killed the poison in Windows environment, don't forget to kill it in DOS mode again.
Tips: Generally, antivirus software can be used to directly use the disk to enter DOS mode to prevent viruses after booting, but this may not be the case for some antivirus software downloaded online. Some require you to make your own antivirus disk during installation, and usually you cannot automatically enter DOS mode to automatically kill viruses. At this time, you have to find the antivirus program file of the antivirus disk yourself and start it in DOS mode as a command. So how to find it? The method is as follows:
1. Put a floppy disk that has been made for anti-virus in the DOS environment into the floppy drive.
2. Carry out antivirus testing in Windows environment.
⑴. First open the floppy disk in Windows, and then open the DOS window from "Start - Programs - MS-DOS Mode".
⑵. Move the mouse to the taskbar and right-click, select "Horizontal Tile Window" or "Permanent Tile Window" in the pop-up shortcut menu and click, so that it can work in the A-disk window and the DOS window at the same time.
⑶. In the open floppy disk file, see which files with the word "EXE" (i.e., program files with the extension EXE), and enter it as a command into the MS-DOS window, and then see if it can be started and checked for viruses. If it cannot be found, then look for the next file of this type to test until it is found. After finding and testing, it can be confirmed that it can be run. Then press the "ESC" key to stop the program, and then copy the file name of the antivirus engine with a pen, as a command to kill viruses in pure DOS, and finally close the MS-DOS window. Note: Some antivirus floppy disks do not support antivirus in DOS mode in Windows environment, such as Rising 2001 standard version. At this time, after finding the file of the antivirus engine, it will give a prompt, which can also be confirmed that it is the file of the antivirus engine.
㈢. After entering a pure DOS environment, it can be used to prevent viruses. The commands required to start the antivirus engine when performing antivirus in pure DOS mode are the same as those required to perform antivirus testing in Windows environment.
4. Use the principle of manually killing the virus to check to see if the virus still exists.
If it is those viruses that are difficult to eradicate, even if you use the above methods to kill them, it will be difficult to kill them completely. This is the case after my computer is infected with the Happy Hour virus. What should I do at this time? First, you need to delete all files that can be infected but not important. For example, files that are easily infected during Happy Time are mainly "htm" or "htt" and "asp" files. Most of these are web-based files, which are not very important. After my computer was infected with this virus, I deleted all the "historical" files in IE and E-MAIL in OE. Then, you have to find ways to kill the virus by hand, and then flexibly use this principle to search for any files with the virus. For example, according to the information, the method to manually kill the Happy Hour virus is to first find out all "htm" or "html", "htt", and "asp" files to see if their source files contain "Rem I am sorry! happy time". If so, it means that the file is dyed with Happy Hour and delete the file. In fact, based on this method, I can also use it to check whether there is still a Happy Hour virus on my computer.
Tips: After killing the virus, check whether there are still viruses on your computer. You can use the "Start/Find" "Find" program to check, which will save time and effort. The method is:
①. Obtain the characteristic encoding unique to the virus (usual viruses have it). For example, the characteristic encoding of Happy Time is: the source file with poison contains "Rem I am sorry! happy time".
②. Enter these feature codes into the "Include text" of the "Find" program and start searching.
③. If you can find such files, then look at the time they have been modified. If they are recent, it is very likely to be poisonous files.
④. Further determine whether it is a poisonous file according to the inspection methods of different viruses.
Using this method to check can save the trouble of checking a large number of related files, greatly improve work efficiency, and the inspection results are accurate. Generally speaking, all files with the virus code on your computer can be searched in this way (I realized this technique later and proved to be feasible after repeated trials. It is much more advanced than the method of retrieving virus files in the article "Full Elimination of "Happy Time").
5. Manually delete the program files used to explain and run the virus.
If all the methods are exhausted and the virus cannot be completely eliminated, it is best to delete the program file used to explain and run the virus without affecting the execution of important programs. For example, to explain the running Happy Hour viruses, if they are determined that it is difficult to completely eliminate them by using all methods. If you delete some program files and make some programs you want to use fail to run, you can completely eliminate the virus and confirm that the virus is no longer recurring before reinstalling the damaged program or system.
6. Notes:
⑴. Don’t trust the experts too much.
After my computer was infected with Happy Hour virus, I read a very authoritative article saying that only files such as "htm", "htt", "html", and "asp" will be infected with the virus. However, after my manual inspection, I found that the ".dbx" file of "deleted email" also contained Happy Hour virus (this is because it contains E-MAIL files). After discovering it, I used three antivirus software to check it in turn and couldn't find the virus.
⑵. Pay attention to when using multiple antivirus software to prevent viruses:
Multiple antivirus software cannot work at the same time, otherwise it will easily cause a crash or even fail to turn on the computer due to incompatibility. I have had this experience, and at that time, the entire system almost crashed. The correct way to operate is to use an antivirus software to close it immediately after killing it (but you don’t need to remove it, and if you install it, you will generally not have conflicts), and then use another one to kill it, and take turns to it.
⑶. Antivirus should not be too frequent.
If you are always anti-virus for dozens of hours a day, you may have killed all the computer hard drives before they can be killed. A classmate of mine once taught this lesson.
⑷. If you don’t know how to use manual detection and killing the virus, don’t think that this requires a lot of professional knowledge to do it.
When you know what kind of virus your computer is infected with, you only need to search for some professional antivirus websites or websites such as "Rising, Kingsoft Antivirus, KV3000" and other antivirus software. You can usually find relevant information.
⑸. If you are afraid that antivirus software will destroy some important files, you can use antivirus software to check the virus first, and then further processing will be done after checking whether there is a virus or what kind of virus is found.= All rights reservedHot Network Hot downloads
If it is found that it is a "Happy Hour" virus, we only need to kill the relevant files. This will not only prevent some unrelated files that are easy to kill, but also speed up the speed of detecting and killing viruses. If you have relevant expertise, you can also use manual antivirus, which is safer.
⑹. Ask professionals for guidance.
If you use all your efforts and are not a "opponent" of the virus, you can go to some professional antivirus websites to find their webmaster's E-MAIL address and OICQ number and ask them for advice. You can also post on their forums or some comprehensive portal computer virus forums, and you can also email them to the manufacturer of the antivirus software you use, and ask them to help you solve the problem.
