Pop up that suggest the election of scan or not scan a USB Device
If Sophos can detect and block the USB devices, I think that Sophos can add a Window message to help the users to Scan the USB keys when this is connected to PC. With this manner if the user have selected the option once, for example, when connected the first time to the PC the second or next times he can cancel the process.
The Sophos message is "Simplicity" and the idea is provide a "Simple" option to users to scan your USB's or other medias when it's are connected to the Pc's.
