How to remove a virus from a flash drive It is very easy to detect a virus on a flash drive; it shows itself when you open the flash drive and error information appears. This happens very often; in some cases, all information from the flash drive is hidden or deleted. Moreover, even the conductor does not help to open it; an error appears in an unknown language, reminiscent of hieroglyphs.
