Sounds like autoplay is disabled which I recommend it should be as a prevention method. Keeping Autorun enabled on USB and other removable drives has become a significant security risk
due to the increasing number of malware variants that can infect them and transfer the infection to your computer. 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 another 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. Read Danger USB! Worm targets removable memory sticks
