Thanks Vic,
My system is a generic Intel PC, not Toshiba. I use F-Secure Internet Security, Adaware, SpyBot S&D, Win Defender. I was using (in addition to CCleaner) Privacy Guardian to clean out my system routinely. Just before I started getting these error messages about the corrupt file, I uninstalled Privacy Guardian. Here are the details of the latest "popup" error window from Event Viewer and the Microsoft Link:
Application popup: CCleaner.exe - Corrupt File : The file or directory \System Volume Information\_restore{000CD547-0129-4B27-B8E2-A61171E8ACE7} is corrupt and unreadable. Please run the Chkdsk utility.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
OK, so I clicked the link, and here's what I got:

So, if I take the above at face value, perhaps I am missing a driver CCleaner needs, or this driver is corrupt? One other note....just before the balloon pops up, and CCleaner is well into 'Run Cleaner' mode, my A:\ floppy drive lights up.
Thanks again,
