Majid,
Are you trying to scare the kid away from the music? You must be kidding when you make suggestions like that to a classical newbie!
Tolsk,
Look as some of the threads in music. Use your search thread button and put in some of these composer's names: Vivaldi, Mozart, Bach, Beethoven and see what recordings have been discussed. Search violin music as well. You will find a whole bunch of suggestions of good recordings.
I would suggest you start with Mozart and Beethoven as they are very accessible. then move on to Bach. Vivaldi is also accessible so he is a good place to start. Brahms, Tchaikovsky (try his Serenade for Strings and Souvenirs de Florence -- they will probably sound very familiar to you) are also good starting points. Just go to the library if you have access to one and get some music and start listening. Another good way to break the ice is to listen to classical radio or one of the cable tv music stations (like listener's choice which is offered by the Time Warner Cable systems). That way you will start getting an idea of the things that intrigue you. NPR also has good classical programing. If you have itunes and broadband, they have some streaming radio. Listen to the classical offerings in headphones.
After you have some idea of what you like, come back and post a thread to ask for suggestions from composers.
