My file in Win 7 is 625 K. There was some talk about viruses being associated with a file like that, but without the 32. If you do a search for the file, does the archive show the same size as the one in the system32 folder? If it was different, the system file scan should have caught it. You could probably find somewhere to explain how to replace a file and I will check on it. You may have to take ownership to change it. Have you run any other type of anti-virus scans?
