U disk poisoning The files in it are gone, but the capacity is still so much, how to solve it?

Recently, the virus spread through the mobile storage (this article is collectively referred to as the USB disk virus, also known as U disk, flash disk, mobile disk) is raging, so that many friends who often use mobile storage devices in public places are depressed--- and they are caught in the trick without paying attention, but they can't kill them all, and they are very helpless.

Why does the USB drive virus run automatically?

First of all, let's analyze the propagation principle of USB disk viruses: the spread of such viruses mainly relies on the files in the root directory of USB drives. It is a configuration file in the form of text, which we can do with text software, and it can only be located in the root directory of the drive.

This file contains commands that need to be run automatically, such as changing the drive icon, running program files, optional shortcut menus, and so on.

The file structure is simple, consisting mainly of a fixed segment identifier [autorun] and a custom autoplay command. Once you define the autoplay command, you can implement your own autoplay. Therefore, as long as the creation of files can be prevented, the virus on the USB drive loses the ability to spread.

Prevention and control methods. Create a folder called in the root directory of the USB drive. This takes advantage of the principle that files with the same name (including extensions) and folders cannot coexist in the same directory. Since the virus can't create files, it can't spread anymore.

I think if the file is very important, don't check it first, you go to another computer to try, some computers are poisoned and will still display the file, then you kill it again. Kill the poison, if it really doesn't work, and the file is not important, then it's better to get rid of it.

If it's a useless file, just format it.

If it's useful, just go to the next USB flash drive on the Internet to turn and kill.

You use it after you kill the virus.

pause>nul

exit is shown in the figure below.

3. After completion, save it in a USB flash drive. It can be named "Show Hidden Files cmd", and the save type is "All Files", after completion, double-click the file just created in the USB flash drive to restore it, as shown in the figure below.
