Files missing post virus removal?

I got the System Tool computer virus on my computer last night (still not sure what triggered it, but that is not the issue at the moment). I downloaded the RKill software to remove it and deleted the Trojan Horses from my system. When that was done and I had restarted my system, my files were still missing from my computer. The directions I was following said to download Unhide.exe and run it, which I did. This restored about 10% of the files I had on my computer. I had a few things (things for grad school and a very few pictures) saved on disks and flash drives (which I have not yet put back onto my computer), but the majority of my files and pictures seem to be gone. Even when I search from the Startup menu, I cannot find them. Do I need to take my computer to a shop and have them try to restore the files or is there something else I can do to restore these files myself? I'm able to access the internet on the computer, but I am accessing e-mail through my school computer for the time being.

Thank you so much for your help.
