I have been encountering a strange phenomenon just the past couple of days or so. Sometimes, not always, when scrolling on the bbs, I’ll suddenly get a download entitled “swiphy20141103.swf”. If there is already a copy in my downloads, I get the icon popping on down to the download folder in the dock but it doesn’t make another copy of it there.
Google doesn’t really tell me anything useful.
