Computer Restore + iTunes Question

I've came to realize that computer virus suck and that I should get a mac rofl but that's not the point...I've gotten a virus and well, I mad to do a computer restore which wiped my hard drive (I knew it would do that), thus deleting iTunes + all the music and apps etc.. Well, before I got the virus I had my iPod all backed up with all the music etc...I wanted (not know I was getting the virus). And so I did the Computer restore like I saiud, downloaded iTunes, and synced up my iPod touch. Well, I was browsing my music library on itunes and I noticed the some of the music wasn't all on iTunes. Well it was the music I had from CD's I had ripped to iTunes and put on my ipod. Well how do I get those songs from my CD's that are ripped on my iPod back to iTunes with out re-ripping the CD's??? Cause I know my dad will be furious that some of the CD's I ripped + the ones he ripped aren't on iTunes/computer. So, how do I get the songs onto iTunes with out re-ripping the CD's?
(The CD's weren't stolen etc... we owned them)...

Thanks!

P.S.: If I can't get the songs I ripped onto my ipod back on to the computer can I have some excuses why I can't or some lame excuse please lol....

 

Is there anyway around this somehow if I jailbreak maybe??

 

Thanks!! I'll check it out. Any other ways people?

 

Hmm I guess I'll try that before I DL that program someone else mentioned.

 

UPDATE:

I tried backing up my ipod a 2nd time the songs from CD's didnt get put onto the computer. WHY APPLE?!?!??!
