How an autorun.inf file can be affected
The autorun.inf files are just a few small configuration files used in Windows, to tell the operating system what action to take with the disk drive where this file is located.
When we say drive, this can be a flash memory, a cell phone, an MP3 device, a portable hard drive or an internal hard drive of your PC.
In this case Windows assigns a different letter to each of them when you install them and when you find an autorun.inf located in its root, it executes the action specified in it.
Windows will automatically run the file “lindo.exe” without asking the user of the Laptop or PC where you connect your MP3, which is nothing more than a virus that will immediately penetrate and infest the computer.
One of the actions that this malicious program will do, will be to create in all available hard disks an autorun.inf file identical to the one that was in your flash to assure its propagation and start when the system loads these drives.
This only means that if you bring home in your flash memory a virus within it that penetrated by inserting it into a PC at your school or your work, if it does not have the autorun.inf the virus is unable by itself to penetrate your system.
So the best way to avoid the effect of autorun.inf temporarily is by pressing the Shift key when connecting the memory to the PC and not releasing it for 6 to 8 seconds.
Note that if you open the browser and double-click the memory icon, the default action will be performed.
On the other hand, autorun.inf files have hidden, read-only and system attributes so when you examine your flash memory in the browser you won’t see them.
In addition, antivirus programs do not detect them as they are not considered a virus and it is logical since they are widely used in applications that have nothing malignant, for example, the installer disk of your operating system or the drivers of your PC all have their autorun file included.
