I have used ad-aware twice today, and each time. I get an error "the file or directory C;\windows\system32\proquota.exe is corrupt and unreadable. Please run the chkdsk utility" I have re-installed ad-aware, and am happy that the program is not corrupted, so what does this mean? I have tried to run chkdsk, but am unfamiliar with it. I think I have run it in read only mode, and got another message "deleting index entry proquota.exe index $130 of file 11379" Do I need to worry about this, or not? Any advice wouod be greatly appreciated.
