I can confirm that it is only the Lounge (and perhaps one or two other forums from the "Community Collections" category) that is private. I have browsed this part of the forum many times as a guest.
Also as far as I know, a surprising amount of antivirus programs still detect old Macintosh viruses. Obviously I'm not sure what algorithm Google use, but if it's anything fairly mainstream it will probably detect the viruses. Furthermore, the site containing the viruses hosts a number of more modern (and PC) viruses as well, so Google might well just detect the link to that site, and find fault with the 68kmla simply because it links to a site that hosts viruses (although I'm not sure whether or not they do that). Also I seem to think that I found that site itself with a Google search (or at least re-found it like that) but I can't remember for sure.
