As the OS gets more popular, Apple will need to add the kind of protective features present in Windows to deal with this sort of problem. Dismissing it isn't gonna work - this kind of malware is the problem these days rather than viruses. As a savvy user, I've never found the need to run antivirus software on Windows, but it would be the height of arrogance for me to scoff at the problems others do have and blame it on their stupidity.

As is the way with these things, Apple will stonewall, but I expect eventually handle the issue. In the mean time some of the congregation will snort in derision and deny there's a problem.
