Apple apparently shipped a few Video iPods containing the RavMonE.exe malware (apparently, its a Trojan which opens a backdoor in your PCs security). It's not an awful piece of malware - it's well documented and just about every competent anti-virus program will stop it.
The interesting part is Macs are not vulnerable to this malware, only Windows PCs.
Apple would NEVER do anything like this on purpose, would they? Of course not
