Hidden Files cannot be unhidden.

In this case, most of them are computer viruses, and most of them are USB flash drives. This virus mainly hides folders (and cannot cancel hidden attributes ), create an executable file with the same name as the folder and the icon is the same as the folder but with the extension EXE (most of the files are virus files ), the virus then disables the display system file, display hidden file, and display extension options on the computer. This makes it easy for a cainiao to disguise the virus, even veterans who have been using computers for years are very easy to cheat.. Then spread around with the USB flash drive until the user thinks it is a folder and double-click the executable file. There is no response on the surface, but you can tell you without a doubt that your computer is poisoned, unless you have installed anti-virus software that can detect or kill the virus.

When someone finds out that it is too late, but he needs to open the folder, and then open the options for displaying system files and hidden files to delete executable files, this option is dimmed when you are about to unhide the folder property.

Here is the solution. Open cmd: Press win (the Windows icon buttons in the lower left corner of the keyboard CTRL and ALT) + R to open the "run" interface, Enter cmd, and press Enter.

Switch to a USB flash drive or another partition home directory that needs to show hidden folders: Enter the drive letter, such as H: In the CMD window, and press Enter.

Enter attrib *. *-H-S/D and press enter to create the attrib. Then, we will find that not only the file is displayed, but also the hidden options can be modified.

This is why, because the virus prevents users from modifying Folder Options and changing folders into system files, users cannot modify the hidden options.

Is there any good way to prevent USB flash drive poisoning. I have a good solution: anti-virus software first. In addition, we need to develop a good habit, that is, right-click the USB flash drive and choose to open it. Because when you double-click to open the USB flash drive, if there is autofun in it. INF file, and the file defines the automatic running file, it will be very easy to poison, so the Autorun. the inf file can be deleted without hesitation. in addition, you can tell whether the icon is a file or a folder by placing the mouse over the icon. If the information such as the file size is displayed, It is a file; otherwise, it is a folder.
