Why does USB disk poisoning always cause problems?

What is Autorun.inf?

autorun.inf is one of the common files that is used to automatically run the specified file when the disk is double-clicked. However, in recent years, some people have used the autorun.inf file to spread Trojans or viruses. It takes advantage of the user's misoperation to execute malicious programs, thereby invading the computer and causing serious impact. This behavior poses a significant threat to computer security.

When the file is on the USB flash drive and inserted into the computer, the system will automatically read the contents and execute the specified program in the background. This is the principle of the USB flash drive automatically spreading viruses.

How to prevent the virus in the USB flash drive from spreading to the computer?

When we insert the USB flash drive, we can hold down the [shift] key on the keyboard until the computer recognizes the USB flash drive. Doing this will prevent the USB drive from running automatically, thus preventing the spread of viruses.

How to prevent the Autorun.inf file?

Since the virus spreads through the autorun.inf file, then we will start first and fight the virus with virus.

1. Open the root directory of the USB disk, create a new folder in it, and then rename it to autorun.inf.

2. Press and hold the [win] R shortcut key at the same time to open the run window, enter cmd and press Enter to open the run command window.

3. Enter the following command and press Enter

md G:\autorun.inf\U disk immunity...\

Be sure to enter the last 3 dots and backslash. In addition, the G above represents the drive letter of your USB flash drive. If your U disk is D disk, enter [d:\autorun.inf\U disk immunity...\], if it is H disk, enter [h:\autorun.inf\U disk immunity...\] And so on.

Finally you will find that there is an additional folder named [U disk immunity...] in the autorun.inf of the U disk. But this folder cannot be deleted.
