Stop Trojan Infection

A Simple way to disable any antivirus, worm or Trojan from entering your USB drive is to create a folder by the name of "autorun.inf ". 

Once this done, right click on the folder, navigate to properties, hide the folder as well as write protect it. This works as well with a text file of the same name. This ensures that even if a virus, Trojan or worm does get into the USB drive, it does not being to operate as soon as the USB drive is plugged in.
