Don’t ask, don’t tell…Apple’s policy on Mac malware

Posted by essjae on May 19, 2011

Ars has a wonderfully insightful article with internal Apple memos regarding the Mac Defender malware.  The best part, Apple says to tell customers:

  • Do not confirm or deny that any such software has been installed
  • Do not attempt to remove or uninstall any malware software
  • Do not send escalations or contact Tier 2 for support about removing the software, or provide impact data.
  • Do not refer customers to the Apple Retail Store.  The ARS does not provide additional support for malware.

Even more telling: “Apple’s [IT] department mandates the use of Norton Antivirus on company machines.”

“Specifically, effective immediately, Microsoft will support Windows Server2008 R2 Hyper-V to run CentOS. CentOS is a popular Linux distribution for Hosters, and this was the number one requirement for interoperability that we heard from that community. “
