- My questions are:
- 1. Why did the sysadmin COMPSURF the server?
- 2. Is there definite proof that the virii came from the demonstration disk?
- 3. What was infected by the virii? Why were executables left unprotected
- from infection by network users? Or was the demo run from a supervisor
- login? If so, why?
- 4. If the network was previously infected, perhaps the demo disk was infected
- from the server. Why couldn't the person with the demo disk ask for
- compensation from the company?
- 5. How were the virii found? What prompted the search?

- Nope. I don't have any. The closest I've come is discovering Michelangelo
- on ONE computer - before the "deadline".

- I don't see a reason right off for ANY compsurf at all. The infected files
- could possibly be disinfected by F-PROT or CLEAN or ...; at most they could/
- should be deleted and restored from the original diskettes. If (big IF)
- NET$OS.EXE was infected (how did it get infected?) then perhaps just a regen/
- reload of NET$OS.EXE. I think that compsurf is a drastic and quite radical
- fix for the problem. It should be the extremely last thing done, IMO.

- I doubt that the date/time of infection could be fixed with any certainty.
- I don't remember the particulars on these virii but most non-trivial virii
- do manipulate any/all information possible to hide themselves. However, I
- suggest that you post your questions to comp.virus and see what is said on
- that group.
