Deleting problem

Hey guys
I have a deleting problem that I don't know how to handle.

I have the following folders that I want to delete:
c:\program files\xerox\nwwia

I want to get rid of the xerox folder, but I can't. I tried these commands in dos:
c:\program files\> delete xerox
c:\program files\> deltree xerox
c:\program files\> delete xerox

Then I tried the same commands for nwwia.
The folder still won't go away. I tried to look for it in regedit, but I couldn't find it.

The xerox folder looks very suspicious and contain to files besides the subfolder nwwia (which don't contain no files either).


Can somebody help me out?
Are there any other ways to go inside the core of the pc to delete files...?

Jam it back in, in the dark.

This sounds scary to me.
What if virus and trojans has this kind of protection. How the hell are we supposed to get rid of them?

Anyways, thanks for replying Domino.
If anybody else have another theory, please do inform.

How ya doing, buddy?
