Has anybody seen this: RENAMEDBYADMWHILEHIDDENTOALLOWDUPLICATEACCELERATORS It is appearing as the title of PDFs everywhere. I have just found one on our council web site. If you G for it it returns over 500 matches, all of which have nothing in common. Is this a kind of virus? Anybody know anything? Aaron Wall makes reference to it here: http://www.seobook.com/archives/000408.shtml, but recieves no replies. Did anyone get to the bottom of this? Any help appreciated. simon.
