    This method will work only ,if any Linux OS is installed in your PC (I used Ubuntu).Just start Linux OS.Plug your Pen drive.Open your Pen drive by the system.You will find the files which are affected by Virus which are some time invisible in Windows.Just delete all the files(Right click on the file -> Move to trash).That is enough.(If it is not working,Can't delete,do it again by removing and connecting you pen drive to PC).
    I Fount this method because,none of the solutions which I got from the Internet didn't worked.
    I wish this will work.
