[comp.virus] Scan v67 and killer.com

Bill.Viggers@comp.vuw.ac.nz (Bill Viggers) (10/14/90)

	There seems to be a little problem with the latest version of
	Scan and its related products.  Killer is (I think) locally written,
	and is designed to remove the STONED virus.

	When I ran Scan v67 it picked up killer.com as being infected with
	the invader virus.  Thinking that I actually might have the virus
	I used clean to fix it up.  This unfortunatly seems to have
	destroyed killer.com.  Checking further, I discovered the invader
	virus on the version of killer.com given to me by my dealer.

	Having successfuly used killer.com before, and the 'virus' not
	having spread, I was a little surprised, and used scan v67 to
	check out killer.com that was on a pc at VUW.  That too it appears
	had this virus.

	The documentation for Scan v67 said that the invader virus is a new
	virus, and that was why the release of this version of Scan was
	delayed.  Putting 2 and 2 together, I assume that this means that
	killer.com has some code in it that Scan uses to identify the
	invader virus.

	If anyone who could either confirm or refute this, I would
	appreatiate it.

This appears to be the case, although our own testing is no finished yet.

In any event, I would suggest that people, in New Zealand at least, no
longer use KILLER to treat the Stoned virus. We have released a new
program, NOSTONE, which handles both the original Stoned and a new
variant with an altered signature (and one of several new messages,
including "Donald Duck is a liar.") Recent versions (post 64) of
McAfee's SCAN also know about both versions of the Stoned virus.

NOSTONE is available on our publicly distributed collection of
anti-virus utilities and it will be available for anonymous FTP very
shortly; like wait a day or two. The files will be in /usr/local/ftp
on rata.vuw.ac.nz
