If i use a wireless keyboard on a computer with a virus via plugging the USB transmitting thing into it. Can any known virus corrupt that little USB thing and move with it if i then plug that USB thing back into a clean computer at a later date?
No because the usb is a Bluetooth transmission not a storage device, if you connect any storage device on the infected computer and then on the clean one then you will infect the clean one (if it doesn't have AV), is important to know that phones count as a storage device.
