The extended attributes are inconsistent.

"The extended attributes are inconsistent"

What does this error message mean? It comes up when I try to install a program or even when I am working with a program like Excel, for example. The window just shuts down and this message appears.

Thanks.

Welcome
I think the quick meaning is corruption.

Try the following

System Restore
SFC Scannow
Repair Install if you have a Vista DVD

Hi. Thank you for answering my post. I cannot use System Restore and I cannot install any downloaded programs because the error message pops out. I also don't have a CD to re-install.

I have Spyware Doctor and it doesn't show any malware or virus. I cannot try Windows Defender because the error message "The extended attributes are inconsistent." appears on any program I try to call.

I'm hoping I can do something from the Safe Mode but I do not know what to do.

Thank you again.
