- Subject: Hard Drive Protection from nVir Virus (Mac)
-
- I am a new subscriber to the Virus-L list. I subscribed in hopes that
- someone could possibly give me some information or advice. I need to
- find a hard drive write protection tool. This is my problem - my macs
- were infected with the nVir virus. After extensive cleanup and losing
- a lot of good applications I placed the Vaccine into my system files.
- It has been brought to my attention that the users either Turn Off the
- protection or remove the vaccine so they may be able to use their
- infected applications. What can I do in this situation. This campus
- is new to macs and I have only worked with them for about a year.
- This has become very frustratinng. Can someone help?

- However, this would assume that the system is already infected. When
- a disk is inserted, no code is executed from the disk in question.
- System code, already in place from the current booted system, is
- executed. There is no method for a floppy disk to infect a system
- merely by being inserted into the machine.

- Okay, the following is based on my personal experiences here at Apple:
-
- I don't know to whom the message referenced above was mailed, but I
- can assure you that the possibility of Apple shipping any software
- with a Virus is almost nonexistant. We have a group whose sole
- responsibility is to ensure the clean build of our software. This
- Software Configuration Management (SCM) group has implemented a
- variety of strategies to help ensure a sterile environment:
-
- 1) All build machines are not connected to any network.
- 2) All software is built from source files that have been stripped of all
- resource forks.
- 3) All software is built from source files. No software is allowed to be
- submitted with pre-existing resources.
- 4) All software is built using tools created here at Apple. This means
- that we build the tools, as well as the software. The tools are built
- using the same procedures as any other software.
- 5) All software is checked after build using a variety of tools such as
- VirusRx and ResEdit. The checking is done on a image copy of the built
- software, not on the originals. (To prevent potential infection from the
- tools, even though they are also kept only for this purpose.)
- 6) All originals have at least one copy kept off-site, at least one copy
- kept on site in a locked vault, and additional copies (the ones actually
- used) are kept in a locked room, only accessable to members of the SCM
- group.
- 7) The copies sent to manufacturing for duplication are never inserted
- into a machine for use; they are only used in an image copy duplication
- machine.
-
- There are other measures as well. To sum it up, Apple Computer is
- VERY aware of the potential problems of virus infections. I find it
- EXTREMELY difficult to believe that Apple has shipped any infected
- software. Whoever responded to your original request had a plausible
- explanation; an infected dealer may use diskettes from a machine, put
- them back, and pass the infection. Naturally, Apple has no control
- over such circumstances. Only dealer education and safe software
- practices can help.
-
- As you say in your message, "...trust Apple. Their business depends
- upon it."

- Subject: Viruses and the Media
-
- Nicholas Geovanis is correct to point out that the unprofessional
- treatment of viruses by the media is a part of a larger problem. His
- comments about US News & World Report are well deserved. As American
- news magazines go, however, US News is one of the better ones (usually
- less sensational than Time or Newsweek, for instance). What surprises
- me is that reporters for the newspapers and magazines are not better
- informed about viruses than they are, considering the fact that many
- if not most of these reporters use computers on a daily basis; they
- are as vulnerable to viruses as anyone.
-
- But I guess if you live in the world every day and don't bother to
- inform yourself about what's going on before reporting it, you
- probably wouldn't bother yourself about data integrity either.
