Files Vanished After Using Pc

My computer was infected with a System Restore malware. I used the real windows system restore to roll back the system to a point before the infection started. It worked, and the computer returned to normal function as far as applications are concerned. However, my documents and pictures disappeared from the hard drive (no thumnails, no filenames).I tried to undo the system restore, but this did not resolve the problem and the virus reappeared, so I rolled it back yet again. I downloaded Glary Utilities and tried the file restorer and thousands of files were found, but none of the files I am looking for appeared.
