[comp.virus] Virus spread

Preston@DOCKMASTER.NCSC.MIL (02/28/90)

Is Jerusalem-B spread an indicator of the future?

Jerusalem-B (Israeli variant) was apparently shipped about 1 week ago
in a PC AT clone from one of the smaller companies.  It was on a
formatted hard drive with MS-DOS 4.01 installed.  The company
confirmed that they had been having a problem with that virus when
contacted by the upset owner.  An earlier contact with the company had
resulted in a denial of a virus problem, and a claim of shipping 300
systems per day.

The new owner, being innocent in the ways of viruses, had, within an
hour, infected his master copies of Microsoft Works and an income tax
program, and now has ordered replacements.

This is the same virus shipped by the Census Bureau several weeks ago to
about 300 users, according to published reports.

There have been detection tools for this virus for months, rather than
weeks, as in the case of some of the newer and "better" viruses.

So far, indications from my experience and surveys are that most
companies and users wait to learn from personal experience about
viruses, rather than learning from others.

Are these infections (with an old virus) an indication of what will
happen when the large number of new viruses have had time to spread far
enough?

Or will the increasing availability of virus scanning tools and
self-checking programs (like MS Works) intersect the "infected systems
curve" soon?

I don't recall seeing an "average rate of adoption" study for techniques
to counter new classes of threats to information systems, but it appears
that it may be in the 10%/year range or lower, at least initially.
