3.7.1 Release Notes (July 9, 1997)

Version 3.7.1 fixes an error which could sometimes cause crashes when
scanning very rare kinds of files while pass the new "more lenient"
check for damaged resource forks which was introduced in 3.7.

3.7 Release Notes (July 7, 1997)

Version 3.7 detects a minor variation of the MBDF B virus which was
properly detected by the 3.6 INIT but not by the 3.6 application.

The Disinfectant manual now discusses the Microsoft macro virus problem.
The introductory text displayed in Disinfectant's main window warns that
Disinfectant does not recognize the macro viruses and refers the user to
the manual for more details.

The "All Disks" command in the "Scan" menu has been changed to "All
Local Disks". This command now only scans local disks, not network
AppleShare servers.

The "All Disks" command in the "Disinfect" menu has been changed to "All
Local Unlocked Disks". This command now only disinfects local unlocked
disks, not network AppleShare servers or locked disks like CD-ROMs or
locked floppies.

If you want to scan or disinfect servers, scan or disinfect them
individually, or use the "Some Disks" commands in the "Scan" and
"Disinfect" menus.

In version 3.7, the check for damaged resource files is more lenient.
Some very large resource files like the "Netscape Resources" file used
in Netscape Communicator strictly speaking violate Apple's rules, but
seem to work OK in practice. Version 3.7 no longer considers these kinds
of files to be damaged.

This version fixes an error which could sometimes cause Disinfectant to
quit with a strange alert message. For example, in some very rare
circumstances, it could quit with the message "^0 is already open" when
scanning Photoshop. The alert message was supposed to be Disinfectant's
"Out of memory" message.

We made a separate change to make it less likely that Disinfectant will
fail with the "Out of memory" alert. Also, the "Out of memory" alert
message has been expanded to give more information. It now tells you to
use the Finder's "Get Info" command to give Disinfectant more memory and
try again. The "OK" button in this alert has been changed to "Quit".
