Cannot Delete file from Desktop

[Guest]

I recently ran an index of my hard drive (using Google Desktop application)
or it could have happened following the installation of Norton's Security
application, don't know which one caused the event as I installed both at the
same time. After the indexing or installation was complete 4 files appeared
on my Desktop that I didn't have before. I attempted to delete them but
received the following error message: "Cannot delete file: Cannot read from
the source file or disk". Checking the attributes they are all listed as
system, with "0" bytes. I feel they are remenent files from a former
install. I have searched the knowledge base without results. How can I
delete these files from my desktop?
