Flash drive infections usually involve malware that loads an autorun.inf
file into the root folder of all drives (internal, external, removable). When the removable media is inserted, autorun looks for autorun.inf and automatically executes a malicious autorun.bat file which calls wscript.exe to run autorun.vbs on your computer. When a flash drive becomes infected, the Trojan will infect a system when the removable media is inserted if autorun has not been disabled.Reconfigure Windows XP to show hidden files, folders
