In order to reduce the number of such alarms, please observe the following procedure before reporting a virus: 1. Download Virus-RX (the latest version) from the virus directory. Put it on a floppy disk and write-protect the floppy. You can be sure that Virus-RX is free of know viruses because it checks itself for infections and changes its name to "Please throw me in the Trash" if it finds anything. 2. Download a fresh copy of the file you suspect from sumex. Without running it, put it on another floppy and write-protect the second floppy. 3. Use Virus-RX to scan the second floppy. If you find an infection, be sure to let us know about it. If you don't, look elsewhere for sources of infection before telling us about it. The only problem with this procedure is that Virus-RX does not detect the ANTI virus, so if you suspect an ANTI infection you must check the file by hand with ResEdit or use Virus-Detective.

Also there is no good way of entering large numbers of accounts yet. What's more Apple considers the formats of the Appleshare accounts file proprietary so we cant write an application to add and delete large numbers of accounts at a time. We also understand that there is a upper limit to the number of accounts you can have on an AppleShare server that no one can really determine, but which may be as low as 2000. I recommend you do what we are doing, look at MacJanet >From Waterloo Microsystems. It was developed by and at a university which has to deal with these kind of administrative problems. Apple Computer does not really care much anymore about educational sites and their problems at least as far as I am able to determine from their support and responses. ------------------------------ Date: Fri, 17 Mar 89 12:32 EST From: "Kevin Cole at Gallaudet U. Washington DC" <CADS_COLE%GALLUA.BITNET@cornellc.cit.cornell.edu> Subject: New electronic music list There's a new list for those of you who like to play with synthesizers and micros. It's been up for about a month now, and I'm helping the moderator get the word out about it. Here's the info: EMUSIC-L@AUVM.BITNET (and EMUSIC-D@AUVM.BITNET) EMUSIC is a complementary pair of lists (EMUSIC-L for undigested mail, EMUSIC-D for the moderately edited digest) devoted to the discussion of Electronic Music. Topics of interest include (but are not limited to): synthesis methods, algorithmic composition, psychoacoustics, timbral research, instrument design, MIDI troubleshooting, new tricks for old machines, musique concrete, pedagogic methods, performance techniques, reviews of current and historical musical and technical trends, announcements of events, papers, homegrown sounds and software. The EMUSIC-D FILELIST contains the archive of the discussions to date as well as data files, programs and other materials of interest to the Elec- tronic Music community. To add yourself to the list, send the command SUBSCRIBE EMUSIC-L Your_Full_Name (for undigested mail) or SUBSCRIBE EMUSIC-D Your_Full_Name (for digested mail) via mail to LISTSERV@AUVM.BITNET or LISTSERV%AUVM.BITNET@CUNYVM.CUNY.EDU (Internet) where Your_Full_Name is your real name (not your userid). To remove yourself from the list send the command SIGNOFF EMUSIC-L (or SIGNOFF EMUSIC-D) Moderator: Eric Harnden <EHARNDEN@AUVM.BITNET> ------------------------------ Date: Thu, 16 Mar 89 18:28:00 PST From: jln@accuvax.nwu.edu Subject: nVIR A and B There has been some confusion over exactly what the nVIR A and nVIR B viruses actually do. In fact, I don't believe the details have ever been published. I just finished spending a few days researching the two nVIR viruses. This report presents my findings. As with all viruses, nVIR A and B replicate. When you run an infected application on a clean system the infection spreads from the application to the system file. After rebooting the infection in turn spreads from the system to other applications, as they are run. At first nVIR A and B only replicate. When the system file is first infected a counter is initialized to 1000. The counter is decremented by 1 each time the system is booted, and it is decremented by 2 each time an infected application is run. When the counter reaches 0 nVIR A will sometimes either say "Don't Panic" (if MacinTalk is installed in the system folder) or beep (if MacinTalk is not installed in the system folder). This will happen on a system boot with a probablity of 1/16. It will also happen when an infected application is launched with a probability of 31/256. In addition, when an infected application is launched nVIR A may say "Don't Panic" twice or beep twice, with a probability of 1/256. When the counter reaches 0 nVIR B will sometimes beep. nVIR B does not call MacinTalk. The beep will happen on a system boot with a probability of 1/8. A single beep will happen when an infected application is launched with a probability of 15/64. A double beep will happen when an infected application is launched with a probability of 1/64. I've discovered that it is possible for nVIR A and nVIR B to mate and sexually reproduce, resulting in new viruses combining parts of their parents. For example, if a system is infected with nVIR A, and if an application infected with nVIR B is run on that system, part of the nVIR B infection in the application is replaced by part of the nVIR A infection from the system. The resulting offspring contains parts from each of its parents, and behaves like nVIR A. Similarly, if a system is infected with nVIR B, and if an application infected with nVIR A is run on that system, part of the nVIR A infection in the application is replaced by part of the nVIR B infection from the system. The resulting offspring is very similar to its sibling described in the previous paragraph, except that it has the opposite "sex" - each part is from the opposite parent. It behaves like nVIR B. These offspring are new viruses. If they are taken to a clean system they will infect that system, which will in turn infect other applications. The descendents are identical to the original offspring. I've also investigated some of the possible incestual matings of these two kinds of children with each other and with their parents. Again, the result is infections that contain various combinations of parts >From their parents.

Sometimes, Word files that once contained several thousand characters of text are turned into empty files. In other words, someone creates a Word file on the server (both Word and the file are on the server) and saves it, and everything is fine. If that person quits and someone else opens the file from a different machine on the network, the file is empty -- there's nothing there. This doesn't happen very often: maybe twice a week, and it just started recently. The weird thing is that if I change the file type to "TEXT" and then open it again in Word, everything is there. All the weird Word formatting stuff is there too, but the original text can be reconstructed if necessary. It seems that Word is somehow corrupting the file when it is saved. I've never seen anything like this. It could be some strange interaction between Word and AppleShare. I don't want to use the V-word, but I'll say that I checked the server with Virus RX v1.4a2, and we have virus protection software on all the machines on the network. If anyone has ever seen anything like this, let me know. I haven't ever seen anything like it. Incidentally, all the machines on the network run system software version 6.0.2, and we have Word 3.0.2 and AppleShare 2.0.1. -Greg ------------------------------ Greg Brail ST601396@brownvm.brown.edu (401)521-9599 ST601396@brownvm.BITNET ------------------------------ End of Info-Mac Digest ******************************
