Could be any number of low-level disk overwriters, such as those with
the CIH payload (CIH, Kriz, Magistr, some trojans), some Opaserv
variants, and a number of boot code infectors.
Witty will do much the same thing to XP, with the supposed security of
NT and NTFS making no difference whatsoever.

Thank you for your replies. Do the free antivirus programs such as
AVG, Avast and AntiVir protect you from these types of viruses?

Yes they do, or try to. They will fail if:
- they aren't set to scan "that type of file"
- they haven't been updated since the virus came out
- they aren't running, or are set to to scan on access
Those factors have more to do with results than "which av". I'm using
AVG 6.0 (the free one) and it rocks; dunno about the other two.

They should. If you updated it at least once a week. Not
once every two or three years.

That is an important point. I usually check for updates to HOSTS,
antivirus program, antispyware programs and my software firewall
daily. I have concluded that a multi-layered approach to protect your
computer is best. I mean having a hardware and software firewall, an
updated antivirus program, good anti-spyware utilities, HOST file
program, etc.
