Update on INIT-9403 Mac Virus 7 March 1994 This is an update on the INIT-9403 Mac virus, announced on March 3rd. First, we note that the strain of the INIT-9403 virus that was announced a few days ago has been found only on Macs running the Italian version of MacOS (so far). However, we strongly urge you to obtain and run the most current version of at least one Mac anti-virus tool. Second, at least one vendor has decided to call the INIT-9403 virus the "SysX" virus, although they will list INIT-9403 as an alias. There is no common naming scheme for new Mac viruses. The majority of anti-virus vendors and researchers have decided to use the name INIT-9403 as the primary name in an attempt to reduce user confusion. We note the name "SysX", however, as a possible alias in some places. Third, 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. Disinfectant 3.4 and the Disinfectant INIT can both be safely used on all Macintosh systems to protect against all known Macintosh viruses until John Norstad, the author of Disinfectant, releases version 3.4.1 (soon). It will be announced and available in all the usual places where Disinfectant is available: ftp.acns.nwu.edu, sumex-aim.stanford.edu, rascal.ics.utexas.edu, AppleLink, America Online, CompuServe, Genie, Calvacom, MacNet, Delphi, comp.binaries.mac
