Read csv file and create a new file

[io]

Hi,

i have to files. 

First file is a csv file
Second file is a plain text file where each row has a value (text)

I want to be able to create a third file using data from the first file 
excluding the values listed in the second file.

Example:

First file:
-----------

mtgoxeur	12	24	36
mtgoxusd	10	12	14
mtgoxpln	2	4	6


Second file:
------------

mtgoxusd



Third File (the resulting one) :
--------------------------------

mtgoxeur	12	24	36
mtgoxpln	2	4	6



Thanks to anyone that can help
