[..] List hidden files (like gmer or IceSword does)

Hi every body!
I have a question:
- Is it possible with AutoIt to list rootkit hidden files/registry keys/processes? I mean, like does anti-rootkit utilities like gmer or IceSword
- If it's not possible using AutoIt, do you know any command line tool, or external ibrary that would help me doing that.

Thanks!
