I ran combofix. It corrupted my Desktop INI files in my folders.
I can not see the images and folders in some of my folders.

Tuneup Utilities says that I do not have icons in my c:\Windows\system32\imageres.dll file.

I can not put a new Imageres.dll file in my vista OS.

It says I am not authorised to change files, but I only have 1 user account.

It is an administrative account.

I replaced some of the DESKTOP INI files, but it does not work in some folders.

When I click VIEW and a different thumbnail size, it works.

I already tried a System Restore, an sfc /scannow and a chck Disk, to no avail.

Advice?

Thanks in advance.
