There should be an option to immune USB devices (Flash memory, external HDD etc) which can create specially crafted autorun.inf file which can’t be deleted by any software such as Unlocker etc. This option also detects already present suspected autorun.inf file on USB devices and prompt for submitting to Bitdefender Labs for adding its detection (if not present in Bitdefender) and after then overwrite this suspected autorun.inf file to immunize the USB device.
Although Bitdefender already have the separate tool for immunizing the USB devices, but integrate to Bitdefender Antivirus Product would be great.
