DSL Ideas and Suggestions :: NTFS and other utilities for DSL?

I'm brand new to DSL and loving it.  I have it install on my 1gig pendrive.  

I work for the Govt, doing IT help desk stuff.  Everyone here uses WinXP systems running on NTFS.

I'm interested in adding utilities like f-prot, spamassassin and some kind of NTFS utility to DSL, to use DSL to do antivirus and spam scans on these systems, booting up from usb.  

If I can accomplish this with DSL, it could become a sweet Linux solution for us to use.
