really safe to copy data with a USB flash drive and pass it on to each other? In fact, in daily use, there are indeed such safety hazards. You may be caught by accident, and the USB flash drive may not have undergone any security protection and directly copy the data file on some computers and use it on other computers. It provides an effective transmission path for the spread of U disk virus. Some people will say that when using U disk, isn’t it enough to check and kill the U disk first? Can't antivirus software clean up viruses on USB drive? Yes, antivirus software can clean up virus programs on USB flash drives, but now many hackers will prevent virus programs from being detected and killed. Virus programs that have been removed from being detected have a certain chance of avoiding antivirus programs.
U disk "Shortcut Virus" clear method:
First, we click the menu button in the taskbar in the lower left corner of the computer, and then enter cmd in the search prompt box. At this time, we place mouse pointer on the cmd icon, right-click, and click to run as administrator. At this time, we need to enter a command first and switch the operation's drive letter to the English drive letter of the current USB drive. Let’s double-click on my computer on the desktop to check the English letters of the USB drive letter on your computer. The English letters of the U disk letter on each computer are different, because they are all drive letters generated automatically sorted in English. Taking the computer I am demonstrating now as an example, the drive letter on my side is the letter U.
1. We enter the command "U:" in the black window of the cmd command prompt [actually input without ""], and then press Enter.
2. Delete the shortcut virus, command: del *.lnk
3. Quickly restore the infected and hidden original files, command: attrib -s -r -h/s/d *.*
U disk AutoRun Virus protection settings:
A careful friends will find that after the new USB disk we just bought is connected to the computer, a file named AutoRun.inf will be found in the USB storage space. Then I deleted the file directly, but I didn't know that doing so actually made a very big mistake. The AutoRun.inf file was actually saved in by the manufacturer when producing a USB flash drive. To put it simply, when we store files, the AutoRun.inf file can be blocked and virus programs that want to be infected with USB drives. As long as you ensure that the file AutoRun.inf exists on the USB drive, you can ensure that the virus is not written to the USB drive. If you don't have this file on your USB drive, you can also create it manually. The specific creation method is also very simple.
Step 1: In the root directory of the USB disk, right-click and select New text document.
Step 2: Rename the newly created "New Text Document.txt" and name it "AutoRun.inf". At this time, the system will prompt that if you change the file extension, the file may be unavailable. Do you really need to change it? When we see this prompt, we click "Yes".
Step 3: We right-click the created AutoRun.inf file and click Properties. Check the "Read-only" and "Hide" options in the properties, then click Apply and then click OK. This is set up.
Advantages summary: The advantage of setting this way is that even if our USB drive is accidentally used on a computer with a virus, the USB drive will not be infected by the virus. This achieves the effect of automatic protection of USB disks.
Usage tips:
If the AutoRun.inf file is accidentally deleted by us, the USB flash drive protection function will also be invalid immediately. You can recreate it according to the creation method described above.
