Well, we have millions and millions of people using Windows, and in my experience when viruses and malware affect them, they usually blame themselves more than Microsoft. So, no, I don't think they'd put the blame in Apple.
And if that would have been the case, remember the Antennagate? First they told their customers to hold the phone differently, then they said it was a software problem, and finally they said the problem was the antenna, but that all smartphones had a similar problem (which was a lie). So, in that case I would have expected Steve Jobs' reality distortion field in full power blaming everyone except Apple.
