general Trojan help needed!!

[lokisday]

I'm at work and my girlfriend just emailed me from her iPod, saying her laptop had broken. Apparently she got some popup and then her computer crashed saying "harddrive failure" and she briefly got back into it to pull some stuff onto her memory stick but then it crashed again and now she couldn't get into it at all for a moment and then she got back in and it said all her Documents were just gone from the folder.

I know this is no technical information enough to give a decent diagnosis, but I bet you computer experts know this general KIND of thing ....is there any hope for her computer and files??
