- Subject: RE: The Star Trek virus.
-
- There's been some mention of the Star Trek: The Next Generation
- episode "Contagion". The episode seemed to me to be an attempt to
- educate people about viruses. What the episode said to me was, that
- while viruses can be potentially dangerous (i.e. it destroyed the
- Yamato), the solution to them is fairly simple (a shut down of the
- Enterprise computer, clean out effected memory, then a restart). This
- seems to be a much better way to discuss the problem than the
- sensationalism that goes on when viruses are discovered.

-
- Ok, its not a bug, its a design error. It's STILL wrong. If the damn
- thing is going to require its own special blank directory, why doesn't
- it create its own?

-
- [Ed. If the problem was actually due to a design error, as appears to
- be the case, then it is a problem unrelated to viruses that should be
- taken up with the author of Arcmaster.]

- Subject: Disinfectant 1.0 Bugs (Mac)
-
- Disinfectant 1.0 has been released for about a week and a half now,
- and for the most part it seems to be working well. There have been a
- few bug reports, however, and I want to let you know that I'm working
- on a 1.1 release to fix them. It will be at least a few weeks before
- I release it. I want to wait a bit until I'm certain that we've
- discovered all the problems in 1.0. Until then, watch out for the
- following problems.
-
- Some kinds of "damaged" files could cause version 1.0 to hang, bomb,
- or put up its "out of memory" alert. Version 1.1 will do a better job
- of checking for damaged files. If you get a bomb, hang, or out of
- memory alert while scanning with 1.0, try removing the file that was
- being scanned from your disk and then scan the disk again.
-
- Scanning an active server disk in 1.0 is problematic. If other users
- create or delete files or folders while the scan is in progress, it
- can sometimes cause other files or folders to be skipped or scanned
- twice. This is a problem shared by almost all programs which scan
- disks. We've designed and implemented an improved disk scanning
- algorithm for 1.1 to avoid this problem. Note that in any case we
- continue to recommend that you take servers out of production to scan
- them. This is the only way to avoid file busy errors and insufficient
- privileges errors.
-
- Version 1.0 evidently doesn't work at all over a TOPS network. We'll
- try to find out why and fix it if possible. For now you should not
- attempt to scan non-local disks over TOPS.
-
- Disinfectant works on unenhanced 512K Macs with System 3.2 or later,
- but it requires the "Hard Disk 20" file. We overlooked this in our
- testing of version 1.0. Version 1.1 will check to make sure this file
- is present, and issue an alert if it is missing.
-
- Version 1.0 doesn't properly display its icon in the Finder, because
- we forgot to set the "bundle bit" when we shipped the program. This
- stupid mistake will be fixed in 1.1.
-
- If you run 1.0 on a GateKeeper-protected system to try to repair
- infected files, and if you forgot to add Disinfectant to GateKeeper's
- list of privileged applications, you will get "unexpected" error
- messages. In 1.1 we will try to special-case these errors and issue a
- better message that mentions GateKeeper explicitly.
-
- We received reports that in some cases Disinfectant claims that a file
- is infected, even when other virus tools report that the file is
- uninfected (e.g., Virus Rx 1.4a1 and Virus Detective). This is
- possible, since Disinfectant uses stronger checks than most of the
- other tools. The files sent to us were indeed partially infected, but
- not contagious. We'll document this possibility in version 1.1.
-
- The version 1.1 document will correct a few minor typos and errors,
- and we'll add a "Version History" section.
-
- Thanks to everybody who's written about Disinfectant - I enjoy and
- appreciate your notes. Special thanks to those people who have
- reported bugs.

-
- Original-To: david@cs.hw.ac.uk
-
- In your message entitled "Anti viral software and known viruses", you
- referenced two Hypercard viruses, "Dukakis" and "Hyperavenger". If I
- am not mistaken, there is one Hypercard virus, known as "Dukakis",
- written by the self-proclaimed "Hyperavenger"

- Subject: How can I get into VIRUS-L archives
-
- I just discovered that one of our Macs got infected by the "SCORES"
- virus.
-
- Since I'm not generally interested in viruses, I don't subscribe to
- the list, but in this case, I'd like to look at your archives to
- search for messages on this subject. How can I do this?
-
- (Or could someone just forward me anything I need to know?)

- [Ed. This comes up periodically, so I thought I'd include it here.
- VIRUS-L archives are available via anonymous FTP from
- IBM1.CC.LEHIGH.EDU (in weekly format) and from lll-winken.llnl.gov (in
- per-digest format). BITNET readers can get to the archives by sending
- mail (or interactive message) to LISTSERV at LEHIIBM1 (*NOT* VIRUS-L
- at LEHIIBM1). The message should read:
-
- GET VIRUS-L LOGyymmx
-
- where "yy" is the year (88, 89...), mm is the month (01...), and x is
- a letter corresponding to the week of the month (A, B,...). So, the
- archive file for the second week of March, 1989 is VIRUS-L LOG8903B.]

- Subject: administrative message
-
- Greetings all,
-
- VIRUS-L is now up to just about 1200 direct subscribers. Among other
- things, this means that the amount of bounced mail (due to computers
- or networks being down, disk quotas exceeded, etc.) gets to be pretty
- major here. The most common cause of this is when an account gets
- removed from a machine, I get a message back saying "user unknown" for
- every digest that goes out. It's not uncommon for me to get 30 such
- messages in a day. (Violins start playing...*:) Sometimes, bounced
- messages snowball. For example, some mail relays try to connect for 3
- days, and then send back a bounced message once every 3 days for 12
- days. Needless to say, the information flow can be high.
-
- What to do... If the message is obviously due to a permanent thing,
- such as a user being removed from a system, then I remove the address
- from the list. If the message could be due to an intermittent
- problem, such as a network link being down, then I give that address a
- day or two to clean up its act. Having failed that, I remove the user
- from the list.
-
- The moral to this long sob story is this: if you've not received any
- digests in quite a while (a week or so), and/or if you know that your
- e-mail system was down for a period of time, you may well have gotten
- removed from the list, not because I'm out to get you, but because I
- have to try to keep bounced mail (read: time) to a minimum. If this
- happens, please understand, and re-subscribe (if you wish to rejoin
- the list, that is...). (I'll add this to the "welcome" message for
- new subscribers.)
