WinDoctor's Program Integrity reports that five programs "cannot access necessary files"

WinDoctor’s Program Integrity reports that five programs "cannot access necessary files" for the following six DLLs:

 

mfc80.dll        (Symantec Live Update)

msvcp80.dll   (Symantec Live Update, Zone Alarm, Logitech SetPoint)

msvcr80.dll    (Symantec Live Update, Zone Alarm, Logitech SetPoint)

msvcp90.dll   (Avast, Zone Alarm)

msvcr90.dll    (Avast, Zone Alarm)

mfc90u.dll      (Avast)

mfc80u.dll      (Logitech SetPoint)

 

All of these problems are marked with Medium Severity; however, all the programs involved are functioning nornally. WinDoctor offers "No Solutions." Any thoughts?
