Apple has denied that the malicious code dubbed “Opener” is a virus, Trojan horse or a worm. However, the security community disagrees, saying that while the program is not an immediate threat, it is a worm because it attempts to copy itself. “Opener is not a virus, Trojan horse, or worm,” Apple said in a statement. “It does not propagate itself across a network, through email, or over the Web. Opener can only be installed by someone who already has access to your system and provides proper administrator authentication. Apple advises users to only install software from vendors and Web sites that they know and trust.”
