VIRUS-L Digest Wednesday, 14 Feb 1990 Volume 3 : Issue 41
Today's Topics:
Introduction to the VIRUS-L Index
VIRUS-L Index IBM PC Topics
VIRUS-L Index Macintosh Topics
VIRUS-L Index Miscellaneous Topics
VIRUS-L is a moderated, digested mail forum for discussing computer
virus issues; comp.virus is a non-digested Usenet counterpart.
Discussions are not limited to any one hardware/software platform -
diversity is welcomed. Contributions should be relevant, concise,
polite, etc., and sent to
[email protected] (that's
LEHIIBM1.BITNET for BITNET folks). Information on accessing
anti-virus, document, and back-issue archives is distributed
periodically on the list. Administrative mail (comments, suggestions,
and so forth) should be sent to me at:
[email protected].

Subject: Introduction to the VIRUS-L Index
This posting is the introduction to the VIRUS-L Index. Hopefully
these indexes will be helpful to all. I've only been able to index
the digests from January 1, 1990 as of yet, and still I am about a
week or two behind. Should I ever catch up, I will begin to index
back-digests.
I plan to send out about one of these every month or so, and I
would guess that after 3 or so months I will have to start anew, for
the index will get too lengthy. Any suggestions in that area will be
greatly appreciated.
The index's topics are my own personal views on the content of each
article; I have tried to sum up the contents of each in one line. In
the cases that either the topic or the general heading does not point
to a specific article's subject line from the digest, I have included
the subject line in square brackets.

[Ed. Thanks for providing this great service, Karyn! I hope that the
index helps everyone out in going through back issues. I'll maintain
a copy of the index for anonymous FTP on cert.sei.cmu.edu, in
pub/virus-l/archives. Feedback on format etc. is appreciated and can
be sent to Karyn and/or to myself.]

Retailers can re-shrinkwrap s/w 10
Retailers perhaps use tamper-resistant packaging like Tylenol? 11
Get in habit of scanning everything - stores re-wrap and
commercial distributers sometimes have viruses 11
Stores don't do virus checks on returned S/W (case history) 11
Retailers have a "Trial/Return" policy for S/W 11
Vendors can sell s/w on write-protected diskettes 12
Steps a vendor can take to make sure returned s/w is virus-free 12
Some vendors do sell s/w on write-protected diskettes 12
Comment on vendor sell write-prot. s/w [Protecting s/w
from contamination] 12
In the UK they rarely see shrink-wrap; retailer won't demo 12
Someone determined can write on a write-protected disk 13
Most software comes write-enabled 13
Most infections are by the well-intentioned 14
You do want to deal with retailers with a return policy 14
Answer from someone who works in a store [re: some more thoughts
on shrink-wrapped software] 14
Suggest that vendors w/ write prot. disks note that fact on disk 14
Stores can *simply* do a sector-by-sector, byte-by-byte compare
of returned software 15
Why not just run a good virus checker? 15
If someone really wanted to infect a write-prot. disk, they could 15
Dispute V3 #15 (*simply*) 20
Trivial to tweak a drive to think a disk is writable - S/W not
