Sucks you are going to leave at least in part because of this... Just out of curiosity I looked back at slightly over 1 year of posts in Alt OS and didn't find any started by a mod talking about the necessity of AV on a Mac... The percentage of Mac users on this board is incredibly low. Those of us that do post seem to have at least an 'intermediate' level of knowledge about things. So I'm not entirely sure what it is that causes you to want to leave. Losing a Mac user, even if its a casual user, is pretty detrimental to the survival of at least the Mac portion of Alt OS.
