SysX) Damage: Alters applications and system files. May destroy all mounted disk volumes. Spread: Only in Italian version of MacOS so far, but extensive there. Systems affected: All system models. BACKGROUND: The INIT-9403 virus was recently discovered in Italy. It appears that the virus is being spread (initially) by an altered version of a pirated commercial software product. This software, when run, installs the virus on the affected system. Once present, the virus alters the Finder file, and may insert copies of itself in various compaction, compression, and archive programs. These infected files can then spread the virus to other Macintosh systems. The virus is currently only spread by the Italian release of MacOS. IMPACT: After a certain number of other files have been infected, the virus will erase disks connected to the system, attempt to destroy disk information on all connected hard drives larger than 16 Mb, and attempt to completely erase the boot volume. RECOMMENDED SOLUTION: The authors of all major Macintosh anti-virus tools are planning updates to their tools to locate and/or eliminate this virus. Some of these are listed below. ASSIST recommends that you obtain and run a CURRENT version of AT LEAST ONE of these programs. Some specific information on updated Mac anti-virus products follows: Note: An unexpected system conflict sometimes results in Disinfectant 3.4 giving "unexpected error -192" messages when running on Macs with enabler versions 003 (the LC III) and 040 (the Centris/Quadra 610, 650, and 800), and with the 32 bit system enabler. You can safely ignore this error message as it does not signify a real problem.
