The USB flash drive is infected with a nasty folder exe virus [Copy link]

I wanted to copy something to a USB drive these two days. When I used the USB drive, I created a new folder, but after a while I suddenly found that the folder was gone. I created a new folder and it disappeared. I was puzzled for a long time.

Soon I found that all the files in the USB drive had turned into exe files. I was instantly shocked. What was going on? I was completely stunned. I thought I was doomed. I thought everything was gone. Does this virus have a lag effect?

If I didn't click on the antivirus software, it wouldn't respond. If I clicked on any file, the antivirus software would throw it into the quarantine area and delete it. I didn't dare to quarantine it, so I just left it alone. Then I checked the capacity and the size didn't change. The files should still be there, so they must have been hidden by the virus! I quickly looked for a solution.

I guess the computer that was copied didn't have antivirus software installed, and someone else's USB flash drive with a virus was used on it, so the host was infected, and then I was also infected when I copied things...

Fortunately, it was not a serious virus that could cause data loss or hardware damage. I checked online and found a simple solution, which I solved quickly. I'd like to share it with you:

The folder EXE virus hides the original folder, creates an EXE folder with the same name, and creates an autorun.inf file and a Recycled.exe virus file. When the user clicks on this fake EXE folder, the virus will be activated. There are many variants of this virus, and general antivirus software will not prompt it. After the generated EXE file with the same name is double-clicked to run, the virus program is executed, and the folder will still be opened. It can be said that the folder EXE virus is very confusing .

Infection symptoms:

1. The image quality and resolution of the folder are inexplicably reduced, as if mosaics were used, and the icons need to be enlarged to be visible;

2. The capacity of the partition and USB flash drive suddenly decreases, often by 50MB;

3. When opening a folder, there is a sudden delay or even freeze;

4. You want to modify a file extension, but it suddenly disappears after modification, or disappears after a freeze.

5. After deleting a folder, the deleted folder will reappear;

6. Anti-virus software frequently reports viruses;

7. A folder with "Access Denied" appears;

8. End a process (must be a non-system process), confirm that it is not opened again, and the process reappears;

9.autorun.inf appears.

Solution:

First, to display the file extension, open This Computer - View - File Extension;

Create two texts on the desktop, named "1" and "2",

Open "1", copy the following code, and then change the file name to .reg

Windows Registry Editor Version 5.00
[HKEY_LOCAL_ MACHINE\ISOFTWARE\Microsoft\Windows\CurrentVersion
\Explorer\Advanced\Folder\Hidden
\SHOWALL] "CheckedValue"=dword00000001

Open "2", copy the following code, and then change the file name to .bat

for /f "delims=" %%i in ('dir /ah /s/b') do attrib "%%i" -S -h

Then put the two files "1" and "2" into the root directory of the USB drive, click "1.reg" and "2.bat" in turn, then the original file will appear, the EXE file will be deleted, and the file will be restored~

I was scared for a moment. I can't bear to see my data lost now. I have to develop the habit of double backup in the future. When I have time later, I will also run an antivirus program on my USB drive. It should be much better.
