[comp.virus] Help needed on Mac virus attack

SOUTHALL@AUVM.BITNET (Tom Southall) (11/16/89)

Hello,

We are being hit by a Mac virus that is not recognized by our vaccine
programs (Disinfectant, etc.).  The symptoms we see, in order of
severity (age?) of the virus are:

1. System file date changes to current date
2. All printing services are degraded
3. File can not be opened - but is visible
4. Open files can not be saved
5. Machine freezes in the middle of doing work
6. Names of infected files are changed to *'s

The virus appears to be passed through data files and/or through our
Appletalk network.  We have reformatted all disks and fixed the
server, but the virus re-appears very quickly.

Any ideas as to what this might be, and how to get rid of it would be
greatly appreciated.  Thank you,
