DOS virus how to remove 20

It doesn't matter if you don't have a score, I would also like to help you, but your problem is not very clear. Especially the black screen, the reason is hard to say.

It could be that you got something wrong, or maybe there is something wrong with the KVDOS itself, or even something wrong with the DOS system.

Forget it, I'll talk about my operation, you compare it, I hope it works.

kvdos can be made on their own, or they can be made in.

Initiates pure DOS mode into Dwarven DOS. (XP's DOS can't be used for antivirus, Windows is still running, so there's no point.) ）

Enter "D:" Enter.

Type "cd kvdos" (with a space).

Enter "Start the mouse."

Enter "Officially entered."

That's it. Very simple.

Considering that there may be a problem with the DOS system, you can also try other DOS, or even make a DOS boot floppy disk on Win98, or ** make another DOS boot disk. Leave one.

DOS virus is generally only able to run in the DOS environment (boot virus is not limited to the DOS operating system, some early viruses that simply occupy the boot record as a virion can still destroy the boot record of the computer hard disk), and the infected computer virus is the earliest computer virus. DoS viruses that infect the main boot sector and boot sector are called boot viruses, and Mix viruses and viruses belong to this category. This group of viruses is not much in number compared to other viruses, but it is the DOS virus with the highest infection rate.

Simple concept: DOS, DISK

operate

The short name of system is Disk Operating System.

Step 1: Get in and out.

There are two ways to enter the DOS: 1

Click [Start], [Shut down the system], and select [Restart the system and switch to MS-DOS mode]2When you start the computer, hold down the Ctrl key, and when the selection interface comes out, press the up and down arrow keys on the keyboard and select COMMAND

prompt

only, press Enter. Note: If you are using win2000 and win

XP,You have to enter win98 first。

The best way is to make a DOS boot disk when the system is clean, and use it to boot the system, which can ensure the perfect effect of your antivirus! That is to say, when using the hard disk to boot, cut into the DOS operating system (than above: After the selection interface comes out, press the up and down arrow keys on the keyboard and select COMMAND

prompt

only, press Enter. Be more effective!

Exit DOS: Just now we entered DOS, and what you see may be C: Windows>

It means that your current location is in the Windows directory of the C drive (if you use the second method above to enter the DOS, you will see C: > now enter a command WIN immediately after it, and the system will exit DOS and return to the familiar Windows interface. Note that when you enter win, you may see that the computer does not respond, don't worry, the computer is not broken, just be patient and so on.

The command win is easy to remember, win is the abbreviation of windows.

At this point, you will be able to enter and exit DOS, and you have the bottom of your heart, congratulations! You've made it 50 years old!

Step 2: Perform anti-virus in the DOS anti-virus program of the KV in the DOS adjustment hall.

1.Under Windows, find the location of your KV DOS antivirus program, it is in the installation directory of your KV antivirus software, the file name of KV2005DOS antivirus program is called, the location of each of us to install KV is different, the default is installed in C disk, the custom installation location is different for each person, for example, I install it on G disk, then the location is G: KV2005, now take a note of this position.

2.Use the above method to enter DOS, enter the position you just wrote down under the cursor prompt symbol, press enter, you will see that DOS is loading KV's DOS antivirus program, you can enter KV's DOS antivirus interface within a few seconds, select the disk you want to kill or the folder you want to kill, and you can start antivirus. DOS antivirus can kill the poison more thoroughly, congratulations, now the ruler can kill the virus under DOS!

Hehe, you gave me your share.

I'll teach you another day.

It's a matter of telling you here.

Anyway, it's still a sentence.,What you delete under DOS is a virus-infected file.,You're deleting the file together.,If you can do what you said.,You can clean up viruses under DOS.,It's so simple to not hurt the files.,Which I think who writes viruses have to consider changing careers.。

Enter cmd and then enter c:- dir- to see if the system files are all there, whether there are some things that are not installed by yourself, and how to delete the redundant. If you can't see it, type c:

-dir ah, you can see the hidden files of the system files, how to find the redundant files, just list it, just like this, just like c:- dir ah---attrib -h -r -a -s enter will show the hidden , delete it. Just look for it in the system disk c:

The so-called anti-virus under DOS is to make the anti-virus software run under DOS, use DOS to guide the system, and then directly kill the virus.

I haven't heard such a term in desktop antivirus, which seems to be antivirus under normal circumstances (Windows), and there are some service viruses and driver (rootkit) viruses that cannot be cleaned up.

Anti-virus in safe mode is to select "safe mode" when the system starts, and then start the anti-virus software to kill the virus, in this case, some viruses that cannot be removed can almost be killed.

If you want to compare Rising and Kaspersky, you can only know it after using it yourself, because everyone's machine configuration is different, and the usage is also different, so you can't directly say who is good and who is not, or use it to see, and then you can know what is going on.

Method 1 of the DOS starts --- runs--- enter ping enter.
