What is the expected output? What do you see instead?
dump module

What version of the product are you using? On what operating system?
volatility 2.3.1 on linux and windows 2003 the infected one.
The image memory is a vmware snapshot 

Please provide any additional information below.
I think the machine is infected  by some advanced rootkit, tdl4 or something.

Likely the module that once existed at those addresses has since unloaded, but 
you can double check by going into volshell and checking for the PE header: 

$ vol volshell
>>> db(0xf7797000)

Do you see an MZ header?

Welcome to volshell! Current memory image is:

To get help, type 'hh()'
>>> db(0xf7797000)
Memory unreadable at f7797000

Yeah, so the memory is either not allocated anymore or its swapped to disk. The 
driver could also load, move its code to another pool, and then unload. I'll 
close this since its not a bug that needs fixing, but if you need additional 
help feel free to write on the vol-users mailing list.
