There is even an alert on the link you gave to the forums, same VBS:Malware-gen.
Again a big chunk of obfuscated script, I guess pretending to be a Google Ranking Script (do you use that), but it is after the closing html script. The strange thing with that forum link there appears to be multiple HTML pages in one.
See image, this comes after the first closing html tag. I have modified the script to see it easier in the image as it is all on one line and goes on for some way still on the last line.
