Shlayer has been infecting Macs for almost two years. It's a very simple piece of malware (or family, since there are many simple variants), but is quite prolific and successful.
This takes me back to the early days of malware. I recall when there were only dozens of viruses for MS-DOS, but only a handful for Macs. Despite that, infection rates for Macs were significantly higher for Mac environments than for MS-DOS enterprises. (I recall one colleague who specialized in Macs telling me that he typically saw 30% infection rates in Mac environments--at a time when most MS-DOS users couldn't expect to see a virus from one year to the next.)
Macs have always had a kind of security mystique. There is a myth (and it is definitely a myth) that Macs are safer than other kinds of computers. It doesn't matter what kind of computer you use: you have to consider security or you are going to get hit.
