Unwanted uploads
 

Is there ANY way someone can upload a file into your shared folder? I ran Norton Anti Virus today and found a file "romania.eml" that was infexted with the nimda virus. The file itself isn't that big a deal becuse I'm on a Mac, but I'm worried about security now. I'm the only user of this Mac and have NEVER downloaded anything about Romania, no offense to you Romanians...
