This Freeware system tool is simple to setup and operate on the go. Just install the executable, launch it, and completely vaccinate your Computer and any inserted drives. It completely disables USB autoplay, and prevents USB malware from infecting your machine through the flash drive route. Panda USB Vaccine protects your USB by creating a hidden and protected autorun file on your drive. It protects you from USB malware like W32/Sality, W32/Virutas and also the W32/Conficker worm. This is not fool-proof, but it essentially gives you the necessary protection not present in most antivirus and anti-malware programs – paid and free.
