Simplest way to remove Mal/FakeDouf-B

I have 8 incidents of Mal/FakeDouf-B with different file names and all need to be cleaned up manually.

When i click on the threat to get details on how to do this it takes me to a page, http://www.sophos.com/en-us/threat-center/threat-analyses/viruses-and-spyware/Mal~FakeDouf-B.aspx  where it states "Affected Operating Systems: Windows"

I am using Mac OSX 10.7.5 and wanted to know if this threat affects me? and if so, the easiest way to get rid of it?  and even where I got it, so I can try and avoid these sites.

Thanks

JB
