Windows Explorer Folder Properties Issue

[Ohstop]

Window properties shows a folder has 17 files and 81Mb - opening the folder shows only 12 files and 65Mb
Settings are showing hidden and system files
Folder has no subfolders
This is not an uncomment occurance
WHY?

What folder are we talking about? There are certain "super-hidden" files in Windows that Explorer won't show you even if you have selected to show hidden and system files. However, if you see this a lot, then a virus is a likely explanation. What do you see if you use the command prompt? Ideally, download and install a third-party command prompt (say, the free one from JPSoft), and list the folder contents with that one.
