Windows Corrupt File

Hey guys,
right I started up the computer this morning and in the task bar a balloon keeps popping up telling me that
"Windows - Corrupt File
The file or directory C:\$Secure is corrupt and unreadable.
Please run Chkdsk utility"
So I have, several times, but it still wont repair...
...anyone got any ideas how to fix this?
I have windows xp home sp2, and have completed an indepth virus scan with NOD32.
Kind Regards
Benji
