Watsonville, CA - September 9, 1997 - Aladdin Systems announces that it has
recently discovered that a "Trojaned" (a trouble making program hidden
within a legitimate program) called "StuffIt Deluxe 4.5 (DR)" is
circulating on Hotline servers on the Internet. This Trojan Horse
apparently deletes files while pretending to build a list. Aladdin wants to
warn its customers not to download any such file and that StuffIt Deluxe(r)
4.5 will be available in other traditional formats: Direct from Aladdin
Systems, its retailers and distributors. StuffIt Deluxe 4.5 is not
currently available, so users should not download anything claiming to be a
legitimate copy of StuffIt Deluxe 4.5.

"Although we haven't been able to verify this rumored Trojan Horse file
we'd like to pre-warn our customers before any damage is done," said Rakesh
Chabra, StuffIt product manager.

StuffIt Deluxe 4.5 will be available in the next 90 days from Aladdin
Systems. It will not be a downloadable upgrade but will be available on CD
or diskette directly from Aladdin systems and on CD in catalogs,
distribution channels and in retail outlets. Additional announcements will
be posted on the Aladdin web site (www.aladdinsys.com). To be notified of
