In what way a windows virus can affect OSX files? This you need to understand a virus characteristic. It delivers a payload once executed or the condition in right and target the system vulnerability. Windows and OSX have different vulnerability i.e. different kernel, file system etc. What is an executable in windows is not in OSX. So the virus can't execute it's command in OSX where it's not familiar with. A virus exploit the system vulnerabilities.
On the other hand, we can see that OSX is getting a foothold on the computer industries compared to like 10 years ago. OSX user base have grown a substantial numbers, so I would not be surprised if there would be "viruses" written specifically for OSX in the near future. The anti-virus industry is a big money thing. Last time, the OSX user is so small that it's not beneficial or profitable to virus writers or anti-virus companies (which sometimes I think writes these viruses - hahaha conspiracy theory).
p/s - I stand corrected. A quick google on Mac OS X viruses shows a few viruses for OSX already circulating i.e. HellRaiser Trojanhorse aka OSX/HellRTS.D (http://www.securemac.com/hellrtsd.php). Like any trojanhorse, user need to execute the virus first to release the payload.
Another virus Leap-A (probably written as a proof of concept) spread thru iChat IM (http://news.techworld.com/security/5392/worlds-first-os-x-virus-hits-apple/).
And the best thing
