From what you describe, it appears to be a flash drive infection. 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 file to run 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.
