There's a deadly new type of virus about to
wreak havoc with millions of Windows 2000 and NT
machines worldwide.  It uses a technique called
ADS, or Alernative Data Streams, to write itself
into files on NTFS hard disks in such a way that
no existing scanner can detect.

That's the basis of a story which Kaspersky Labs
put out a few days ago.  Kaspersky Labs is an
anti-virus software company and, as if you can't
guess, its scanner is now capable of detecting
these new viruses.

Others in the antivirus industry were quick to
retaliate.  Network Associates said that its
scanner can already detect ADS viruses, but that
no such virus has yet been discovered outside of
the virus companies' research labs so there's no
need for anyone to panic.

At least 2 companies have made available a free
program to detect ADS viruses.  These, we
are told, clearly illustrate that ADS viruses
are far from undetectable and that Kaspersky was
simply trying to scare people into buying its
own software products.

If you enjoy a good argument, keep an eye on
this one. It'll run and run.  The antivirus
software people have never been on particularly
friendly terms with each other, and this episode
does nothing to change that situation.

WinZapper could well be useful for support staff.
But it's also a demonstration of a new type of
tool which could prove highly dangerous in the
wrong hands.  It allows you to selectively remove
entries from the Windows NT event log.  Thus
someone could use it to cover their tracks after
breaking into a server.  You can read more about
WinZapper, and get your own copy, at
