"The Apple iPod incident was not about Microsoft having a hardy operating system, it was all about security and process," Abrams told InfoWorld in an e-mail message.

Viruses on Microsoft's network weren't unusual when Abrams was testing that company's products before shipping them, he said.

"I released software in an environment surrounded by Windows machines. Many machines on the corporate network were infected. We never introduced a virus into the software in the release or manufacturing processes because we had a professional understanding of what it took to release what we were supposed to," he said.

"That Apple would blame Microsoft demonstrates a lack of understanding of remedial security and manufacturing processes. Virus was only a symptom of the problem. Apple didn't know what they were shipping," Abrams said.

Apple did not respond to phone and e-mail requests for comment before this story filed.
