I have a computer that until a few days ago, was working fine. Then, when I turned it on, it wouldn't load XP and infinitly printed a bunch of these ♀. I took it out and put it in my other computer, and I can read it fine, but it's a 40 GB hard drive, and it only shows up as 5 GB in my other computer. As well, it shows none of the files that I had. Is this a virus of some sort? If so, what can I do to get my files back?
