I don't remember the details just now. Anyway, there could be potentially malicious code hiding also in Open Sourced code and it could be hard or not so hard to spot depending on who's reading it. Generally I agree with the idea that it is probably harder to write viruses for OS X. But is really ease the reason virii is ramping in the windowsworld one may ask.
