It’s simple! Create a folder named “autorun.inf” in your flash drive or external harddisk. This technique can prevent auto-running viruses from spreading through your flashdrive or external HDD.
Note that if your flash drive is already infected or if there’s already a file named “autorun.inf” you cannot create the folder. You’ll have to find a way to delete that file first.
To reverse this, simply delete the folder you created, “autorun.inf”.
