Usb driver: deleted by antivirus
 

Please, could anyone help me, I have new mp4 player, touch screen, radio, pc camera, 32 gb, I phone copy.
NOD 32 on other compjuter deleted some usb drivers, and now every file I sent from PC to MP4, it says "the file is not exist" .
Other files on MP4 work normally. Is it possible to find that usb driver again and put it in MP4, i.e. how to make MP4 to receive files from PC.
