<!-- AUTO_PROMPT AD END -->

prompts the execution of a script, wgotten and renamed b0x.js (attached)
which performs browser detection, and in the case of Netscape 5+ prompts for the download and install of sbc_netscape.xpi (also attached ;; DO NOT EXECUTE) which if interrogated with zip or jar is revealed to be an install script and a windows executable ( which is so resistant to 'strings' as to appear intentionally encrypted or obfuscated ).

In short it looks like bad news.
