k, this seemed to work for panda:
Code:

Function GetPandaInfo()
 $GetPandaInfo = readvalue("HKLM\Software\Panda Software\Panda Antivirus Lite","Product"),
  readvalue("HKLM\Software\Panda Software\Panda Antivirus Lite","Version"),
  getFileTime(readvalue("HKLM\Software\Panda Software\Panda Antivirus Lite","DIR") + "\Pav.sig"),
  getFileVersion(readvalue("HKLM\Software\Panda Software\Panda Antivirus Lite","DIR") + "\AvEngine.exe")
endfunction
