I found this in hijackthis:
O20 – AppInit_DLLs:  C:WINDOWSsystem32fpfstb.dll

I used Malwarebytes’ FileASSASSIN to delete the file. It couldn’t delete it while running, but needed to restart to remove the file. After the file was removed the FileFixer Pro 2009 has not shown its head.

This is a very nasty one. As it states, you will have corrupt files
(although probably not until you clicked on the download to correct corrupt
files). See this link below. This is brand new apparently and this is the
only info I can find on the Internet about it. The customers PC we worked on
has lost most of his .XLS, JPEG and PDF files (and I wouldn’t doubt .DOC
files as well).
