Since this morning, I have noticed that immediately after using CCleaner to analyze, I have a yellow triangle with a ! appear and tell me:
CCleaner.exe-Corrupt File
The file or directory C:\Documents and Settings\...
is corrupt and unreadable. Please run the Chkdsk utility.
It's never done this before, and now it does it after analyzing, and again after removing the files.
I thought I had possibly changed something without realizing, so I uninstalled CCleaner, and reinstalled, keeping it in default settings (in case I messed it up with my personal settings) and it STILL does this.
