File contains "Happy New Year 96" string (no underscores, but I can't imagine why anyone would like to put it there). Also contains the 65 77 20 59 hex sequence, at offset 0x12B92. Did you contact the author or Aminet administrators?
[edit] It seems version for 68000 does NOT contain the string. IMHO 99.9% the archive is infected.
