Usb disk not saving data due to NewFolder.exe

Hello Board Members,
Few days ago (approx 5-6 days) my PC got infected by New Folder.exe virus so due to that my all folders shows another same name of directory in there and with this my usb drives stop tacking data from my PC whenever I plugin it with my pc & try to transfer some data to usb drive then it shows a message that my usb drive is write protected!! So I use "combofix" & "SDFIX" removal tools for removing the New Folder.exe virus but after cleaning it still my usb drive showing the same message & not tacking data from my PC. Can any one give me soluation plz plz send me the soluation on my mail id it's amitgurudev@gmail.com
Thanks with Regards.
