XP--Programs Missing from All Programs

Hi,

I was hit with the PC Stability and Analysis Report, which has created havoc on my Dell 5150 (running XP).  I have spent several days trying to clean up my pc, running Malware Anti-Malware, Super Anti-Spyware, Spybot Search and Destroy, GMER, DDS, RootKill, and Hijack This.  I even went into the regedit to manually remove any files associated with the virus.  After all of this, I ran unhide from bleepingcomputer.com.  I believe I have removed the virus and restored my files, however, I cannot seem to restore the programs to the Start>All Programs folder.  When I enter in the All Programs Folder, all my applications are listed but many of the folders are listed as empty.  I can open up Word documents by clicking individual .docx files, but I cannot find the icon to launch Microsoft Word and other programs.  Needless to say, this is making me a little crazy.  Any help would be great appreciated.  Once again, I truly appreciate any guidence as I am at a total loss about what to do next.  Thanks!
