Ah, McAfee... Yeah, if you look at the site, they still need to work on their detection.
It looks like it is tripping up on the download link.
The technique used is common, but is also something that can be used to intentionally mis-lead a person. Therefore they consider it suspicious (not sure if that is the only thing on the site, there are a couple other coding techniques that can be mis-understood or abused, such as the // links rather than having the full http://. Some parsers will trip up on this thinking that it is refering to a local path, when it is redirecting to a different server).
But, yeah, I would almost be willing to put money on the fact that they are just having a tiff about the download link having an OnClick event associated with it (since the OnClick and override and redirect the page before the HREF is even followed).
