Now many users realize that viruses are very harmful to computers, and installing an antivirus software is a necessary thing. The antivirus software installed under Windows has a very friendly graphical interface. You only need to press the mouse twice to complete the antivirus, and there is no need for too much professional knowledge.
However, there is a big disadvantage to using antivirus software under WINDOWS. If the file being called is infected with a virus, the antivirus software will be helpless. The antivirus software will recommend using the antivirus program under DOS to prevent virus.
But in this era when floppy drives are approaching elimination, many users have already eliminated floppy drives. It is very difficult to prevent viruses under DOS, but we can use our creativity to use other accessories to replace floppy drives, and complete antivirus under DOS.
The USB drive is one of the tools that can complete anti-virus under DOS. Now most USB drives are simulated as floppy drives or even hard drives. In addition, most motherboards now support USB drive startup. Here I will teach you how to use USB drives to create anti-virus drives under DOS.
Create a DOS boot disk
Users can use the UFD Utility program that comes with the USB drive to complete this step. After running UFD Utility, click the "Disk Cut/Format" tab, check the option "Make a boot disk on the flash disk", and then click "Execute" to complete the production of the DOS boot disk.
Create DOS antivirus disk
Here, the author chose Jiangmin antivirus software to create DOS antivirus disk. First of all, we need to make the files required for the DOS antivirus disk. To create a DOS antivirus disk, we need a floppy drive, but there is no floppy drive, so we can use "SUBST" to virtually use a floppy drive. The specific operation is: first create a new folder, for example, create a new KV folder under the C: disk, and then run the "Command Prompt" in "Start-Program-Attachment", enter the root directory of the C: disk, enter "subst a: KV" and press Enter to complete.
Run Jiangmin Antivirus software, then select "Tools - Make DOS Antivirus Disk", remove the hook of the "Make Emergency DOS Startup Disk" option, and then click Start Production. After a few seconds, the first disk is completed. At this time, copy all the files under C:KV to the USB flash drive, and then press the next step on the program that makes the DOS Antivirus Disk. It will be completed in a few seconds and you can exit the program. Then copy the file under c:kv to the USB flash drive again. DOS antivirus disk is completed.
DOS to kill viruses
Insert the USB drive into the USB port, restart the computer, enter the BIOS setting program, set USB-FDD to the first position in the computer startup sequence, and save and exit. At this time, the computer will enter the DOS state. Then enter "kvd2003" at the DOS prompt and press Enter to enter the antivirus program under DOS. Use the graphical interface to easily complete the antivirus.
