Preventing hard drives from being formatted by viruses? Two ways to easily get

More and more virus programs are destroying computer data, and some viruses directly format hard disk partitions. Today we will learn the following two methods to prevent the virus program from destroying the hard disk format.

Method 1: Lock DOS Command Method

The basic principle of this method is to limit dangerous DOS commands to prevent illegal use of these commands to destroy hard drive data. The specific method is as follows:

Open the Autoexec file in the root directory of the C drive with “Notepad” and add the following statement to it:

C:\\>DOSKEY FORMAT=Bad command Or filename!

C:\\>DOSKEY del=Bad command or filename!

C:\\>DOSKEY deltree=Bad command or filename!

Then save and exit Just fine. When you call the FORMAT, DEL, DELTREE, etc. commands, the Bad command or filename will be displayed and the operation will be rejected. If you need to format the hard disk in a special case, what should you do? You can enter the command: C:\\>DOSKEY FORMAT= (Enter), so you can freely operate the hard disk. .

Method 2: Move External Command Method

Prevent hacker programs or malicious code from illegally formatting and modifying hard disk data. You can rename or move related DOS commands to other directories and format them later. You can change the file name back to the hard disk by specifying the C:\\Windows\\format.exe file, changing its file name to format.txt or moving it to another directory, if it is in "My Computer" If you don't see the extension of the file, you can select “Tools →Folder Options →View”, and remove the hook from the extension of the known file type ” In addition, you can use the Windows optimization master to lock the format command, but the basic principle is to rename the format command.

Although the above method is simple, sometimes it can only prevent the gentleman from being able to prevent villains. If someone else is booting from a CD or floppy disk, the same way to format the hard drive. Therefore, using the above method also needs to cooperate with the BIOS settings, set the boot order of the computer to boot only from the hard disk, and add a password to the BIOS, so that it can be foolproof.

When you encounter a hard drive that is maliciously formatted, which method would you choose? It depends on your own choices, and the small series is not too strong.
